Question: I underwent a colonoscopy with a general anesthetic in late December. Within 48 hours I broke out in raised red small pimple rashes on my arms, legs, thighs and buttocks (larger red rash). Two months later the red pimple dot rashes that were on my arms and thighs seem to have resolved after using a topical cream. However, I am still getting a recurring red rash spots on my the upper part of my buttocks which become itchy and seeps slightly when it arises. Other then that, it looks awful but is not painful in any way unless I touch it. When I look at pictures on the internet it concerns me it could be herpes - but there is no continuous itchiness or painful fluid blisters. The rashes also looks like eczema (which I have on my elbows) and fungal infections. My question is can a colonoscopy cause this reaction? I have never had any issue of rashes on my buttocks before.

Thank you

Hi Dr.

I went through 2 images. As mentioned there is no pain at all associated with the rash.

Thanks Dr K. As you can imagine I am very please that from the photos you don't think this is herpes. I didn't think it was.

Just 3 last questions please:

1. How long should I take the medications

2. Would the raised red dots (that were itchy and now resolved) on my arms, thighs etc be related to this condition?

3. If not the lubricants, medications used in the colonoscopy ., what could have caused this condition in your (broad) view?

Many thanks

Dear Dr K

I just uploaded 3 pictures of 2 new spots that have just appeared on the side of my left buttock. They are hard in form, do not itch and are not red. Do you think this is related to Eczematous dermatitis? Or from the topical cream I am know using? Just want to make sure again this is not likely to be herpes. Thanks and appreciate your comments.
