Can Benedryl be taken for rashes on the hands and feet due to Bactrim?

my son has developed spots on his legs and face we took him out to play in the snow had two layers of shirt and pants on him and when we came in and took his pants off he had just red spots all over his legs he has had them for several days now and they seem to get darker when he gets hot and usually midday at night they do not look as bad almost as if they are going away then the next day the same thing happpens about midday they start to look worse is this heat rash of some sort ?

My 10 year old had a bump on the outer part of her vagina, close to pubic bone. Had a fever for 3 days, went to ER and they prescribed her with medicine for an abscess. Now she broke out in a rash and complained of burning while urinating. Noticed now she has a sore on the lower part of vagina which is why she is burning. What could these sores be from?

Hi, may I answer your health queries right now ? Please type your query here...(To preface, my son has an egg allergy and has been unable to get a lot of the vaccines given to children at his age.) My 18 month old son has had a fever varying from 101 - 103 Monday thru Wednesday night. It has been controlled by alternating tylenol and ibuprofen. I took him last night to our after hour clinic to be sure it wasn t an ear infection. Ears looked fine, but his lymph nodes were swollen and his throat was red - Strep test came back negative. Said it was probably a virus. He woke up this morning with no fever, so I assumed the virus had taken it s course. However, this evening, I have noticed a rash on his belly, back and neck. they are small red bumps that aren t raised very much. They don t seem to be bothering him too much. I hate to take him to the doctor again if it s nothing, but I don t want to ignore something if it s potentially dangerous for him. Should we give him Benedryl? Should we take him to the ER tonight or wait to talk to my doctor in the morning?

I have pain and swelling under my upper arm on both sides. I am 70 female.

Dear doctor thanks for your valuable reply however my further query is for last two weeks I have a mild rash under my eye which is persistent and is not going away...I had read somewhere in the webmd website that facial rashes are the first sign...
