How long?: If it lasts over 6 weeks, see an allergist. If it is short term, try some otc antihistamine up to 4 x the regular frequency but watch out for drowsiness. Otherwise topical Hydrocortisone cream should be tried. If it still did not work, see an allergist. ...Read more

Get that looked at: Any infection on the skin from a puncture wound by an insect or animal which is becoming red, swollen, and hot to the touch is potentially showing the initial signs of an infection. What you don't want it to be is a MRSA type of infection so you'll want to get ahead of this thing quickly. Clean the area with soap and water at least 2-3x daily until you see the doctor and stay well hydrated. ...Read more

ITCHY BACKSIDE: More history helpful but sounds like some form of dermatitis; skin inflammation after contact with something to which your body (skin) is overly sensitive. Since it appears from your description to be localized to one place, you might try a combination of topical (skin cream/ointment) Benadryl (diphenhydramine) and Hydrocortisone. Let me know how that works... if not affective... we can discuss other options. ...Read more

Hives?: A rash that comes and goes within a day is most likely to be hives, one of the most miserable and frustrating of benign conditions. By now you have probably thought of every possible food or other trigger but come up with nothing. Sometimes a careful history with your doctor can uncover a known cause. If not then then the long term outlook is good but NO ONE knows HOW long. ...Read more

I have a bright red (and itchy!) rash on the back of both my legs, between my butt and knee. It looks like small bug bite like bumps. Not spreading.?

I have a bright red (and itchy!) rash on the back of both my legs, between my butt and knee. It looks like small bug bite like bumps. Not spreading.?

Many causes: Rashes are challenging even when the doctor can see them, so even harder in this forum. Small red bumps on both legs make me think of reactions to clothes, or something in contact with that area on both sides. Bites can do it. It could be heat rash, a reaction of the skin to warmth and occlusion from pressure. Some drug reactions can do that as can conditions like eczema and psoriasis. ...Read more
