Hi there Eric. It seems your little tryst with the dermatologist's assistant set you back a few bucks! & by the look of things, you still have the 'blood blisters'. If cryotherapy
(cold/freezing ) has been done, more often than not 'blistering' occurs therafter. Please try & take some good close-up snaps of the region & upload it onto this site or use our premium segment 'ask-a-doctor' & get in touch with me should you desire privacy. I look forward to hearing from you to help you further as with this description albeit exhaustive, it can be one of many things including 'milia' or 'warts'. Also please be fiorthcoming with your sexual history & check with your partner/partners hitherto if they have similar lesions. Cheers!
