Other than Dr Anantha is now retired, another bad news is my burning itch has return. This is definitely not the wriggly kind of itch when the wound heals. This is the itch I had since more than a month ago, long before my surgery, the reason why I made so many trips to hospitals, the one that cause me to decided to have hemorrhoid remove. I do not know anymore who to seek help. I am thinking hard what causes the itch to come back and there's many suspect:

Prunes that I started to eat yesterday.
Diarrhea caused by prunes irritates/burns the inside of my anus.
The Lui Cha I ate this afternoon that contains "chai bok"
The gel the doctor used when he inserted his finger to anus
Daflon that I started on. Prescription is 2 X 2 times a day, but I started with 1 this afternoon and later 2 after dinner.

I am seriously depressed now, I do not know where or who to consult anymore. I even try assuming I am having yeast infection and sit myself in water with Apple Cider Vinegar, but nothing works miracle. Heaven knows whether I can sleep tonight with the burning itch. I pity my co workers who have to handle my job because of my frequent absence from work, my hubby who has to take leaves to accompany me to so many trips to clinics and hospitals.
Tham, I didn't know if my friend has the exact problem as you (cellulitis) but the draining concept you mentioned certainly rings the bell. I did a search and from Webmd

"Cellulitis is a skin infection caused by bacteria. Normally, your skin helps protect you from infection. But if you have a cut, sore, or insect bite, bacteria can get into the skin and spread to deeper tissues. If it is not treated with antibiotics, the infection can spread to the blood or lymph nodes. This can be deadly."

Yes, my friend started out with something like skin infection on legs, then spread deep within with fluid buildup. Went to SJMC and the doctor (I do not know which one) suggested the procedure just like the one you did. Pain was reduced but not for long, everything became worse. He can't walk and leg swollen, has to quit his job and rest at home. I know he went to a few hospitals but all treatment doesn't work. In the end went for Chinese medicine, improved a little. Just when he thought he can start working again, symptom came back again. The only thing (I don't mean this sarcastically) I really thankful for him is he came from a generation of landlord family so he succeeded his family tradition of collecting rentals for livelihood, no need to work while with the illness.
