When you exercise, your heart pumps faster and your blood vessels dilate as a mechanism for heat loss due to your energy expenditure.  With exercising, you are detoxifying your body of unwanted wastes and toxins through sweating.  One reason you may be itching is because of the release of  these unwanted wastes through the skin.  This should resolve after exercising and having taken a shower. Another more probable reason is that your blood cells release their histamines, and these mediate the itchy sensation you feel.  This should also resolve after exercising. Not everybody has the same reaction to increase physical activity.  Good luck!

90% of the time, itchy skin is merely a sensitivity to something in your environment--it's the other 10% that you'll need to be concerned about.  Itchy skin can be a symptom of certain cancers, such as Hodgkin's Disease Lymphoma.  I ask you, are there other symptoms such as unexplained weight loss, night sweats (drenching amounts of sweat that only occur while sleeping), or fatigue?  Even if there isn't, I'd still recommend seeing a doctor, who can use some simple blood tests to determine whether it's worth further examining.\n\nYou may also be experiencing allergies to something such as detergents (I doubt this one, or you'd be itching everywhere clothing touches you), dust, soaps, shaving creams or gels, or even certain foods.  Think back to when this all started, and see if you can remember any changes you made out of the ordinary.  You may also try changing your razor if you shave your legs; sometimes the blades of mass-produced razor heads aren't in exact allignment, and the tiny little scrapes that they produce--even if you didn't feel them when they happened--can become irritated and make your skin itch.  In fact, the little bumpy rashes you described fit nicely with this possibly being the problem.\n\nFor relief in the meantime, you can try taking Benadryl tablets along with using Hydrocortisone creams.  You're right to be aware of how much you're scratching, since it's easy to make a bad situation even worse by creating little open wounds with your fingernails.\n\nWhatever you do, please go to a doctor first and work this issue from worse-case scenero first before switching over this and that, these and those.  \n\nGood luck to you!

It's part of the healing process. Itching is a result of the nerve endings around the scar being stimulated. At first, the stimulation is part of the healing. Itching may last months or years afterwards, though, as the scar tissue stretches and again stimulates the surrounding nerve endings.

Actually, the sensation of itching is nothing more than energy being transferred through that area of your body. Two things were happening while you were jogging.\n\n1.Your feet and legs were absorbing impact energy from the act of running. This is no different from hitting the palm of your hand against the table top over and over again. The atoms in your hand swell from the absorbed energy and then once you stop hitting the table, slowly release that energy in an attempt to get back to their normal existing ground state. the transferring or processing of that absorbed energy will feel like itching which is really just a lesser degree of pain.\n\n2.Your legs were also releasing stored energy throughout your leg muscles during your run, adding to the absorbed energy from running. \n\nThis is also why a sunburn will itch like crazy, absorbed solar energy is finding a way out of your body.\n\nAs your body cools down the itching may get worse, because cooling will close your pores, trapping the heat.\n\nHope this helps

When you scratch your itch, you are temporarily paralyzing the sensors in your skin.

No one really knows exactly why people itch in general, actually.  Some people believe itching is a sensation caused by the aggravation of terminal nerve endings, and a response somewhere between no pain and pain.  This is related to chicken pox because most scientists believe that the Varicella-Zoster virus eventually makes its way into the nerves in the skin.  Since the body is trying to fight the virus, chemicals and fluids are sent to the site of infection that cause intense itching (pruritus).  This would explain why it itches even more when the blisters (or vesicles) break, releasing fluid from the blister.  It's in these blisters that chemicals called histamines may be released onto the skin, causing you to feel itchy.

Depends on the cause of the itch. Do you have a rash, or just itching?

when a bug bites you it injects a bit of its saliva and sometimes poison into your skin which causes itchyness so when you scratch any itch it feels better but try not to, it will keep the wound from healing because itching also means its healing and if you keep any wound open it is vulnerable to bacterias and infection.

Eczema can be extremely uncomfortable, because the more it itches, the more it is scratched, and the more it's scratched, the more it itches. This cycle may be triggered by an allergy to a particular food or pollen; it may be a contact dermatitis, caused by a particular fabric, or it might flare up because of emotional tension created by family arguments or anxiety about schoolwork. Eczema should be treated by  the family doctor who may be able to discover its source and prevent further attacks. Advertised cures for eczema cannot control the cause and sometimes make the condition worse.
