My husband has been fighting a monstrous pilonidal cyst for a few years. He had a SiLaC procedure on it in 2023 and we thought it was gone. Fast forward to a week ago and I was checking him for ticks after a hike. The pilonidal cyst has returned, and he also has these little openings where his skin creases on his back. He is overweight but we have been dieting and he has lost 47 lbs so far. We are going back to the doctor who did his procedure on June 2nd, and I got his PCP to give us a derm recommendation because she didn't know what these wounds on his back are. He has these weird patches of dark rough skin in the same area and I thought maybe it was related? Idk im at a loss. How can I care for these until his appointments? He is taking amoxicillin. Im cleaning the wound with an antibacterial cleanser and then flushing with Dakin, then using a non stick gauze to keep the exudate off. I applied a hydrocolloid strip over the biggest hole after the picture and when I took it off today the wound was still open but not nearly as oozing and gross looking as it has been during wound care time. When I first found them there were 3 opening all leaking pus and blood. This is them now after a week of care and antibiotics. 

Im honestly very freaked out, I love my husband and Im terrified. Will it ever get better? Can someone please reassure me because Ive been spiraling with fear for a week. 

How do I care for this? I need some reassurance please, Im freaking out
