Once ina while me finger tips swell up, and get itchy! the first time it happened, it was just my thumb, and i think i was drinking a cold drink, bfor that. the second time, it happened after i was eating greek food and all my fingers on my left hand exept my pointer finger swelled up. nothing has happened since, but sometime when i hold cold drinks i have the same itchy feeling on my fingers but they dont swell up.
