Question : I have a red ichy rash on my knee. I had it replaced 30 days ago. Rash appeared yesterday, about the size of a half dollar, red, raised, itchy. Is this something i can watch for a couple of days or should i seek care now

Hi there.
Yes you can watch & wait.
However in the interim, please apply a cream containing hydrocortisone & fusidic acid twice/daily & it should clear off in 48-72 hrs. If not, then one needs to visit a dermatologist. Cheers & Good Luck!

Nope I dont think it has anything to do with it...have seen a few with similar issues & all resolved & were most likely allergic contact dermatitis lesions. I think you have nothing to worry abut. Godspeed!
