I had fistuletomy surgery about 25 days back. In the first 10 days, i used to get water like clear discharge. For the last 15 days, the clear discharge has reduced, but i noticed this thick discharge. I showed it to my surgeon, and he said the wound is clean and this type of discharge is normal. I am scared. Could you please advise if this type of discharge is normal? I have very mild pain, no fever, no inflammation, no bad odor,  or redness in the wound.
