I was diagnosed with psoriasis about two years ago. After two years of pills and creams, nothing has changed, in fact it has gotten slightly worse. I have always asked my dermatologist to do a biopsy, but he has always told me that it was useless since the signs of psoriasis were evident. After insisting several times, he told me that if he wanted to do it, the cost would be around 15,000 thb.
1) How much does a biopsy to check if it is psoriasis or not really cost?
2) At this point, I would say that I would like to change dermatologists. Could someone, who is perhaps in the same situation as me, recommend a reliable one?
Thanks everyone.
