<s>[INST] Hello. About 5 years ago I had surgery done to remove a perennial abscess/cyst from the cleft of my buttocks right above the anus. There was only thought to be one cyst but when the surgeon removed it they found several others beneath the skin, and while the flesh that was cut away was supposed to be tested, it was discarded by accident. They cut a section of flesh 5 inches long, 1 inch wide, and 1 inch deep. It healed but I have had a tender scar there ever since. Recently I had been experiencing more tenderness than usual and today I realized their was blood and a smelly discharge coming from the scar. I looked in the mirror and it looked like there is a small slit/hole where the scar is. The soonest I can get in to see my doctor is thursday. Another thing is I just went to the hospital two weeks ago because of a cyst on my back that wouldn t pop(I ve had them before) it was a pretty big one and was putting pressure on my spine. It wasn t the first one I ve had on my back, I am very hairy and keep having problems with abbesses. They drained it for me and prescribed me antibiotics. When I was rinsing the wound with salt water like they told me to, some of the water travelled down into the cleft of my buttocks where I had the surgery. Could this be the cause of whats happening to me currently? I just have two more questions, 1. What do you think the problem is? and 2. I just went to the drug store to get bandages to keep it clean and tidy until my doctor appointment, I remember being told to use a product called bactigras when I was healing from my surgery 5 years ago. Is it a good idea to use this again right now to prevent infection and get rid of smelly discharge/bacteria? Any help and input would be greatly appreciated. [/INST] HI, thanks for using healthcare magicIt is likely that you have a recurrent cyst in this area that may also need to be incised and drained.Bactigras is an anti septic dressing that may help to keep the area clean and prevent progression but it would still need assessment.The continued use of an anti septic soap  or cleanser would help to prevent future infections.I hope this helps </s>
