I Have, What We Believe To A Possible Chemical Burn
Drain the blister, topical steroid & antibiotic cream, anti inflammatory
Welcome to ask a doctor service
I have gone through your query and understand your concern.
It is looking an acute burn.
I would recommend you to aspirate the blisters keeping the roof intact.
Also apply a topical steroid antibiotic combination cream like fusidic acid and clobetasol propionate cream on the affected red skin twice daily and take antihistaminic like tablet cetrizine 10 mg twice daily for 8-10 days.
Also take anti inflammatory medicines like tablet ibuprofen.
This should resolve the reaction.
