Hi there. I have a history of mycobacterium marinum in the soft tissue of my right hip. I had to have 3 surgeries to remove the infection and IV abx therapy. Three days ago I noticed a rep spot on my hip above my scar from the surgeries. The spot has gotten bigger and a darker red. I had a temp of 99.9 last night, and today I am getting sharp pains in the area of the red spot. Aslo the spot is hot and tender to touch.

### output:

Hello, I read your message and understood your problem. I think that the infection with Mycobacterium maximum has re-occurred. If you are exposed to the bacteria you tend to get re-infected time after time especially now after 3 surgeries and antibiotic therapy that have weakened your immune system. You must stay way from nonchlorinated water, from pools and swimming. If you have an aquarium at home get rid of it. Exposure to seafood markets or aqueous environments predisposes for the infection.  It is very important to eliminate the chances of reinfection because a long-lasting infection may damage the soft tissues and cause complications. My advice is to see an infectious disease specialist and do some tests. We need to be sure if it is a reinfection with Mycobacterium maximum or a coinfection with some other organism. The antibiotic therapy is a little long-lasting. Usually, patients need to take antibiotics for 4-6 weeks, but sometimes they need a very long treatment 25 months or more. See your doctor again for a proper physical examination and test. If you are still on antibiotics continue them as long as the infection will vanish. Hope this will be helpful for you. Chat Doctor.
