I had posterior fistula in ano which got operated on last tuesday through laser treatment. It has been 8 days since surgery. Now, since last 5 days, I have been experiencing some kind of thick yellowish white fluid inside the operative area. I thought it as pus. One doctor after seeing the picture, he told me that it's pus. Some another doctor told me that it's plasma mixed with motion or a fluid while wound is healing. I am worried that what it is actually. It generally stays there and comes out while gas passing or sneezing. The fluid doesn't have any bad smell. Please let me know that is it normal to have and will subside of it's own through dressing and sits bath? I am currently taking lizoforce 600 bd (prescribed for 5 days) and a pain killer.
