Try going to any clinic 1st and if you're lucky that clinic also perform circumcision and otherwise, they will recommend another clinic that perform the surgery. Well not necessary laser, conventional will do. I did mine ~1.5 yrs ago at a normal clinic near my house for RM350  ..Yeap suffering quietly phimosis & sometime  for ~2 yrs b4 decided to cut off 

I'm also diabetic. So recovering rate is slower than normal ppl. I already >42 when I did that    ..At this age, they will not recommend the clamping way. They will either go for laser or conventional way.. The clinic doesn't hv laser so no chice..just conventional way using blade & scissor.

You just feel abit once they injected you wth anasthetic jab surrounding the foreskin. Therafter just cut off the top part & the pain started when they start to sew back slowly and the anasthetic jab getting lesser...

Pain for the next 2 weeks for sure -YES.. especially the exposed skin touching the cloth & etc..in my case to really recover- It took me 1 ful mth..but worth it - just need to suffer for 1 mth
