Recommend a dermatologist/local clinic

I have recently moved to Bangkok and stay in Sukhumvit 16.

I have a painful boil which is infected and I’m looking for a regular dermat/ general physician who can look and treat the infected boil

Preferably

Private clinic/hospital but affordable

Local go to clinics

Any recommendations would be great. I saw Asok Skin Hospital is near me but I don’t know how good it is? Is it affordable?
