<human>: 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.
<bot>: 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
