Not contact: This is not a contact reaction but a systemic reaction to penicillin if the rash is flat. If it is raised, then they are hives. You will likely get over it in a week or so. In the meanwhile try some antihistamine 3 to 4 times a day. If the itching is unbearable, check with your doctor who may prescribe a short course of Prednisone for you. ...Read more

Is there any need for further testing? I am one of the lucky few to have a true milk allergy diagnosed by allergist due to history of rapid onset breathing trouble with accidental ingestion. I also react to contact with milk on the skin with hives.,
Not now: Since milk allergy may subside with time, retesting in a few years may be helpful to guide you on trying milk again. Since up to 75% of milk-allergic people can consume cooked milk (in baked products etc), what has your experience been with baked goods? There is some evidence that if baked dairy products can be tolerated, eating them regularly may lead to tolerance of the raw milk later. ...Read more

Went to ER with hives on both wrists and forearms and what felt like a lump in my throat. Would the area of the hives suggest it was a contact allergy?
Perhaps, but: Whenever I've been to the ER for similar hives, the doctors tell me that anyone who IDs the exact cause is fooling themselves. The localization can be misleading sometimes, not always, but... You might know if you did anything unusual with your arms just before and if you do - try to avoid that w/o protection. But, it might remain a mystery. Preventive daily Benadryl (diphenhydramine) may help. Ask your doctor. ...Read more
Hives with cold skin: People who have cold induced urticaria release histamine in their skin when it cools. People react at different temperatures. If you place an ice cube on your skin you will develop a hive at the site (see photo). Keep warm, cover skin in cold air, take antihistamines. Swimming in cold water and cold drinks can be fatal. See an allergist for proper diagnosis and treatment. ...Read more
Heat, antihistamine: First avoid temperatures colder than the temperature which causes your hives. Second cover as much of your skin as possible. Third, because the hives are due to the release of histamine in your skin when it cools, antihistamines will minimize or control the symptoms. See an allergist. Avoid swimming in cold water and drinking cold drinks to prevent potentially life threatening reactions. ...Read more

I have Aquagenic urticaria. Is there any medicine to control it. Skin is painful n red after contacting with water. But skin don't itch?
Difficult control: It is very difficult to control this disease and no one has known the actual cause. Some try the regular treatments for urticaria with antihistamines like hydroxyzine, cyproheptadine, and Benadryl (diphenhydramine). Other treatments are more difficult and would need direct care or observations and not enough room here to go into all of the types. See MD-health. Com for further information. I hope this helped. ...Read more
