Hello @thunder_dog88 -- I had reddish brown spots on my legs similar to yours but I had no pain. I do have lymphedema in the legs which I think may be the cause of mine. I did find some information on Mayo Clinic's site about spots on the legs.

I also found some side effects that you could discuss with your doctor if the drug is making it worse.

Are you able to get a second opinion?
