Lupus and allergies are two different types of Hypersensitivity reactions.  A hypersensitivity reaction is when the immune response is detrimental to the host.  Allergies are Type I Hypersensitivity.  These occur immediately and mostly involved premade immune components, such as IgE, histamine, and basophils.  Type I Hypersensitivity is also called Anaphylaxis  Lupus is Type III Hypersensitivity.  This involves immune complexes.  Basically, antibodies bind antigens in large complexes and then are deposited in areas where they shouldn't be, like post-capillary venules and joints.\n\nThere are two other types of Hypersensitivity reactions, Type II, which is mediated by antibodies alone and causes diseases like anemia, and Type IV, which is Delayed Type Hypersensitivity and is mediated by cells like macrophages.  When a person is tested for TB, the resulting immune response is dude to Type IV Hypersensitivity.

The symptoms can be very similar.  Allergic rhinitis (runny nose) is often associated with more sneezing, itchy nose and/or eyes.  Cough is not usually a big part of allergic symptoms.  Runny nose is usually clear.\n\nColds usually do have some cough with them and tend to hurt more with sinus pressure, etc.  Runny nose can be clear or discolored.\n\nOne simple test would be to try a few antihistamines over the counter (claritin and benadryl are examples) - if you are able to take them - to see if they help.  They will usually help allergy symptoms quite a bit, but for colds they do very little.

I've heard both theories as well, I had mono a few years ago, I didn't fully feel well for about 6 months. I had no energy, and tired very easily. Just take it easy, get A LOT of rest. There is nothing you can really do except make yourself comfortable. Hopefully your symptoms won't last that long, mine lasted about 3 weeks, and then I was just really tired...feel better!!!

No ,it's not normal. I also had this many years as a teen and up to my 40s. Dr. said you must have had mono back then, so you're immune system is impared.

Feel much better,and I'm a senior. Go to Dr.until they listen to you. ALSO BE LIVING LIFE DOING THINGS YOU WANT TO.Excersize is not an option .Walking is great. It starts with the first step .Fake it till you make it.It's your life ,laugh ,be interested in things you see on walks,and soon you won't have to fake it. Please let me hear from you later on,so I'll know how you're doing.LOVE YOURSELF!!!!

Allergy to something.

Allergies are immune-system responses to a particular food, airborne substance, chemical, medication, cosmetic, perfume, textiles, building material, or plastic. Some symptoms of allergies are:\n\n    * Itchy, watery eyes\n    * Sneezing\n    * Headache\n    * Runny or stuffy nose, or postnasal drip\n    * Sore throat\n    * Dark circles under the eyes\n    * Itchy feeling in the mouth or throat\nSelf-care for allergies and sensitivities can be approached in a number of ways—but it can be hard to know just where to start. To make it easier, our doctors recommend trying these simple steps first:\n\n    * Watch what you eat\n    * Work with a professional who specializes in food sensitivities to see if certain foods are causing your allergies\n\n    * Clean it up\n    * Control household allergens like dust, mold, and animal dander to reduce your overall allergic load\n\n    * See an allergist\n    * Find a health professional to help you manage your allergies\n\n    * Help children avoid allergies with beneficial bacteria\n    * Take a supplement containing high-potency beneficial bacteria (probiotics) during pregnancy and give them to newborns to help reduce the risk of children developing allergies

Have they checked the oxygen levels in your blood?  Are you Asthmatic?  Sounds like Asthma to me.  Do you have animals?  Shedding is big this time of year... Allergies?  They should check you for either a seasonal asthma or adult onset.  Certain things can trigger asthma out of the blue.  Don't let them just rule you out.  Go somewhere else to get assessed.  They may prescribe albuterol/inhaler for immergency purposes, should your airways get inflamed.  Be sure to stay on top of this... don't just listen to one doctor.. see another!!

Yes, allergies can cause the types of problems that you are describing.  But, like the other poster advised, I would check with my doctor.  I had several of the same symptoms that you are describing along with vertigo and a feeling of pressure in my ear whenever I lay on my side.  It turned out that I had an infection of the eustatius tubes in both my ears.

yes, you can develop allergies later.  they don't develop until after you are exposed to whatever it is you are allergic to.

It may be a nocebo, everyone's nose either clogs or runs after crying, but if you relate it to allergies the nocebo effect kicks in and you THINK you are allergic to something, and thus you "are" :P

go have a food intolerance test done. you may find that you actually eating the wrong types of food, and thats whats making you feel so drained and lethargic. i was feeling like that a few months ago and it drove me insane, as i "thought" i ate correctly, went to gym, and am fairly healthy. went for the test and it showed that i had a sensitivity towards lactose and wheat. ive since cut those out of my diet and it most certainly has made a huge difference in my energy levels as my body was struggling to digest those food items.\n\nand my skin has actually improved too. i know thats not relevant, but there you go...

YES - allergies can start any time.\n\nWhat Is an Egg Allergy?\nFirst, let's learn a bit about the allergy itself. When a person is allergic to eggs, the body's immune system overreacts to proteins in the egg. It thinks that these proteins are harmful invaders and produces antibodies called immunoglobulin E (IgE) to fight them off. Whenever a person who has an egg allergy eats something that contains egg proteins, the body sends out antibodies and histamines (chemicals released from the body's cells during most allergic reactions). This reaction makes the person feel sick.\n\nMost people who are allergic react to the proteins in egg whites, but some can't tolerate proteins in the yolk. The allergy usually first appears when kids are very young, but most outgrow it by the time they're 5 years old. \n\nBecause vaccines are an important part of children's medical care, some people have been concerned about kids who are allergic to eggs receiving flu and measles/mumps/rubella (MMR) vaccines. The vaccines are grown in cultures from egg cells and may contain a small amount of egg protein. Experts say the MMR vaccine is safe for people who are allergic to eggs but advise you to ask your doctor about getting a flu shot. \n\nSigns and Symptoms\nPeople who are allergic to eggs may either feel sick just a few minutes after consuming egg proteins or a couple of hours later. Most reactions last less than a day and may affect any of three body systems: \n\nthe skin - in the form of red, bumpy rashes (hives), eczema, or redness and swelling around the mouth \nthe gastrointestinal tract - in the form of belly cramps, diarrhea, nausea, or vomiting \nthe respiratory tract - symptoms can range from a runny nose, itchy, watery eyes, and sneezing to the triggering of asthma with coughing and wheezing \nPeople who have a serious egg allergy may suffer anaphylaxis (pronounced: ah-nuh-fuh-lak-sis). This severe allergic reaction causes swelling of the mouth, throat, and airways leading to the lungs, resulting in an inability to breathe. In addition, there is a dangerous drop in blood pressure, which can make someone dizzy or pass out, and may quickly lead to shock. For people who are especially sensitive to eggs, even egg fumes or getting egg on the skin can cause an anaphylactic reaction, so eggs should be kept out of the house completely.

Not everyone has the same reactions as you do. Get an allergie test done to find out what your allergic to.
