question: I had a pilonidal cyst removed. a "Biopsy" was performed. and i had stitches. and at the bottom of the stitch it is taking very long to hea. although i already have the middle and upper part of where the surgery was done healed, and i have the scar tissue already. the very bottom still discharges pink fluid. i think. from time to time there is pink discharge. it usually happens a day after i workout my body. and i get a soft bump of sking. then it starts to discharge pink fluid. how can i let this part of the tissue heal?
