ETHANOL ABLATION.. bad experience???

HI.. I am on my third day post ethanol injection: I have NEVER had so much pain from any procedure in my life: broken bones, gallbladder surgery, c section are not like this. I woke up around 4am after the injection .. it felt like a house was crushing my foot: much codeine later it was manageable.. the next day no better: swelling on ball of foot and some pinkness on top: toes splayed with swelling between them: every step is agony: this was ultrasound guided injection.. so either I don't react well or the medical journals dont report the bad responses: on contacting the clinic, the nurse says many people are suffering like this.. which begs the question why are so many people being referred for ethanol ablation if the outcome is not much different in terms of pain and disability than surgery?
Taking 4 rounds of this .. at 4 days off work and significant pain each time doesn't seem a good option..
I have searched and searched the internet but there is nothing much about this procedure (except how good it is!) so I am really curious to know if this is just me or has happenned to others.

Thanks Vicki,... I think I posted the post in the wrong place; I meant to put this under the mortons neuroma discussion.. and yes, it was the 2nd / 3rd webspace....I was thinking it cant be an allergic reaction as it took a long time to swell....
