hi there,i had a local anesthetic on my finger as the surgen needed to drain my index finger since it was swollen with a felon infection.  i now have an rash going down my finger and onto my hand that is small bumps and very very itchy.  I live in Thailand and not sure of the diagnosis.  I was told it could also be due to the anesthetics that were used.
Hello. Thank you for writing to us Rather than the local anesthetic this itchy eruption is most likely a result of contact dermatitis, probably to an antiseptic that was used to clean/ prepare the area, preoperative e.g. Betadine or salon very frequently cause this type of localized eruption at the point of contact. If I was the treating doctor I would suggest an OTC oral antihistamine e.g. cetirizine once or twice daily for a week. Cetrizine is antiallergic and would improve the rashes as well as itching. Topically, I would suggest a moderately potent topical steroid e.g. mometasone furnace 0.1% cream Or fluticasone propionate 0.05% cream, twice daily over the rashes, for a few days. Regards
