Had a sore that kept reapering two times amonth for 7 years. Hadit check two weeks ago, it was a pilanidol cyst, three days later was in surgery, Dr. Said it wasn’t to big but went all the way to the tail bone, he stitched me up and sent me home after 1 week check he didn’t want to remove stitches go back again in 3 Days. In the mean time my tail bone and lower back is liking me incision in leaking a little blood and dark yellow fluid that smells like fish, its gross I’m not seeing any redness more than what was there, but I’m concerned about infection. I have lupus so my immune system is poor and I’m healing slow. My poor husband gags when he changes the dressing.
