Hey I have a rash on both arms really red and itchy and burns and I can't get it to go away should I wrap with ace bandage im not allergic to that?

No you should see : A dermatologist and figure out what the dermatitis is and they can prescribe something to help it go away, or figure out the etiology. Does not sound like compression would do anything. ...Read more

Rashes on left arm and throat swelling, could I be allergic to shrimp?

Rashes on left arm and throat swelling, could I be allergic to shrimp?

You could: Shrimp allergy can be life-threatening and come on suddenly. It's best diagnosed by history -- if symptoms have closely followed shrimp ingestion more than once, you'd be wise to avoid this. An allergist may have additional advice. If the time relationship isn't right, another allergy or something in the angioedema family is a concern. ...Read more

ER doctor prescribed me Keflex for possible mastitis and UTI knowing I'm allergic to penicillin. I am on day 3 and have an itchy rash on arms and legs?

Possibly allergic: Cephalexin (Keflex) and related antibiotics (the cephalosporin group) are chemically similar to penicillinl. Although penicillin allergic persons usually can take them without problem, occasional cross reactions occur -- i.e. you may be allergic to the cephalexin. Check with the doctor who prescribed it. ...Read more

I am having  rash on arm, chest and shoulders, skin redness or irritation and skin rash (episodic itchiness, uniform tiny bumps, skin colored mostly). A nurse said it was allergic reaction & gave me centraben cream. Can allergy last more than a week?

Yes: If you are exposed to the item to which you are allergic, the symptoms will persist, even for years. It would be prudent to consult your doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

Paracetamol allergy; whenever i take my first dose of paracetamol, itchy rashes will occur on my left arm. Having this almost 2yrs and im 30?

Drug allergy: Some people can react to paracetamol, but having the rash only on your left arm is sugestive of a fixed drug eruption and is not necessarily secondary to a systemic allergy. Did using other pain killers, such as Ibuprofen or Aspirin cause any problems? If not you can use them for pain control. ...Read more
