Why would a blister form over a scar?
404535
The tissue of the scar are trying to regenerate.  The blister is part of the process of healing, since underneath is only water inside the big hole. It will go down in matter of time.

There are several issues that can cause bumps around piercings.  Some are related to infection, and may go away. First, remove the earring.. and keep it out.  Place warm/hot compresses on the area once or twice daily.  This may help the bump decrease in size.   \n\nAnother issue that is more difficult would be something called a "Keloid".  This is basically excessive scar tissue from injury.  Cells reproduce to fill in the tissue removed by the piercing.  In this instance, it continues growing because the cells are uncertain when to stop.  \n\nThose who are more prone to Keloids are of Asian or African descent, and tend to be genetic.  Those who are not under those categories can also have Keloids, as I am aware of people with many skin tones, (including very fair-skinned people) who have this issue.\n\nThere are various websites that claim cures for these, although I would recommend seeing a dermatologist or your general physician for treatment.\n\nKeep an eye on it, treat it gently and with hot compresses that will not burn the skin.  If it continues to bother you, seek treatment.  Piercing bumps can effect the remainder of your piercings, and could cause long-term damage.  I would absolutely not re-pierce the ear until you have determined the true issue, and are able to have it treated.\n\nEdited to add:  Please don't use peroxide.  It is not PH balanced.  It is actually harmful to skin..  use alcohol instead!\nBest wishes.

What exactly do you mean by blister?  Does it look like a bump or pimple?  If so you need to go ASAP because it is probably an abscess of a tooth.  If it is due to burning the area with pizza or something hot, make sure you are not re injuring it.  It should have healed by now.  Usually we give 2 weeks for something to heal, otherwise it could be something more serious.  Your dentist may want to do a biopsy of the area if he or she is concerned.\nIn any case, call and make an appointment, better safe than sorry.

That's if a vein, artery or capillary opens. The blod clots, and a scar is usually formed.\nWith menstrual flow, there is no connection to any vein, there is no clotting, it's just a shedding of tissue that has blood in it. If a vein was involved, a 40 year old woman after 300 periods would be a mass of scar tissue!

the best way to keep it from scarring would have been to keep the skin on it if it was a blister....and you should just use cool water, not ice. Ice causes more damage to the skin...it doesn't help it heal because it causes too much constriction of the blood vessels... cover it with bandaids or something, use neosporin and mederma....

It depends on where the blisters are. Flip-flops comfy and try looking up this  product from Scholl. It's a blister "plaster" and after sometime on putting the plaster on the blister, the blister "expands" into this white "bubble" and after a few days (depends on how big/serious your blisters are), when you peel the plaster, there's no scars.

it may actually be beneficial to get a blister, pop it, and let it form a callus so that other blisters do not form. or you can constantly wear a bandaid

it depends on the severity of the wound and your predisposition for scarring.

It is hard to diagnose this, with this little bit of information. It appears that it is a blister. It may have been caused by a burn that you were unaware of, insect bite, allergic reaction to something you contacted or a wide variety of other possibilities. The fact that it is a water filled blister, tells me that the immune response is intact. This is the bodys way of forming, if you will, a protective padded bandaide. This fluid filled sack prevents harmful invaders, like dirt and germs to enter the damaged tissue. It also works to heal. The fluid is filled with many healing substances, that come to the rescue of the damaged tissue. The danger is when the blister is broken. One should never deliberately break a blister. However, if the blister breaks, one should keep the area clean and protected. Neosporin is a good antibiotic ointment to would very similar to the bodys response. It will prevent infection and promote healing. Cover the area with a sterile bandage. You never want to put a dry bandage on a seeping wound, because the fluid will dry on the badage and then pull the healed tissue off when you remove the bandage. If you have done this, soak the wound & bandage in clean & warm water for 20 minutes, then slowly remove the bandage, it should come off without pain or damage. Look for signs and or symptoms of infeaction. Reddness, swelling, pain, green drainage, increased warmth to area or unexplained fever. If the wound gets worse each day, or it not showing signs of healing with a week or 10 days. If there is any loss of functioning, like numbness, etc ...seek medical assistance at once.

Blisters are quite common for anyone who regularly participates in sports. Most athletes just accept them as the price you pay to play, but there are measures to avoid them, or decrease the pain and risk of infection if you find you have one. \n\nCause\nBlisters form when the skin rubs against another surface, causing friction. First, a tear occurs within the upper layers of the skin forming a space between the layers while leaving the surface intact. Then fluid seeps into the space. Soles and palms are most commonly affected for several reasons. The hands and feet often rub against shoes, skates, rackets, or other equipment. Blister formation usually requires thick and rather immobile epidermis, as is found in these areas. In addition, blisters form more easily on moist skin than on dry or soaked skin, and warm conditions assist blister formation. \n\nPrevention\nTo prevent blisters, you need to minimize friction. For the feet, this begins with appropriate shoe and sock selection. Check out more foot injuries for details. Make sure your shoes are the right size and shape. Wear socks made from synthetic blends. Before you exercise, apply petroleum jelly or talcum power to reduce friction, if needed. \n\nBlister Care\nIf you get a blister, you'll want to relieve your pain, keep the blister from enlarging, and avoid infection. Signs of infection include pus draining from the blister, very red or warm skin around the blister, and red streaks leading away from the blister. Small, intact blisters that don't cause discomfort usually need no treatment. The best protection against infection is a blister's own skin. Larger or painful blisters that are intact should be drained without removing the roof. First clean the blister with rubbing alcohol or antibiotic soap and water. Then heat a straight pin or safety pin over a flame until the pin glows red, and allow it to cool before puncturing a small hole at the edge of the blister. Drain the fluid with gentle pressure, then apply an antibiotic ointment such as bacitracin with polymyxin B (double antibiotic ointment) or bacitracin alone. Avoid ointments that contain neomycin because they are more likely to cause an allergic reaction. Finally, cover the blister with a bandage. Change the dressing daily

if you mean the scar that leaves the ugly mark and then it hurts, then i think it is possible that the wound is not yet totally healed. however, if it is from a surgery or a suture, and then it hurts, regardless of how long the mark has been then, i suppose you should see a doctor. it might be sign of some infection or something.

This is normal healing. Try putting cocoa butter on the scar. It keeps it moist and reduces the itchiness. It will also help as the tissue ages to blend in the texture with your skin around it. Apply it up to three times a day.

Not enough information.  When and how did you cut it?  Where is the cut?\n\nIf there is a significant cut, you seek medical treatment.\n\nIf it is small, keeping it covered with a steri-strip might help.  Once it is closed, keeping it moist with Neosporin or other antibiotic ointment will help keep the scaring down.  \n\nGood luck.

Could also be scar tissue from a previous injury.  If there is no site pain, might just have to live with it.  If there is pain or discomfort at the site, or generating from it, best to have it checked out, to rule out something which might be serious (i.e. blood clot - tumor)

you probably have a cold. You are describing normal results after cryotherapy including a large blister. In a week it will be 80% healed and in a month you might not be able to tell where the wart was removed.\n\nsource - personal cryotherapy experiences
