I am a 31 year old woman who has recently had major pelvic surgery 4 weeks ago .whilst in hospital i started with a pins and needles sensation in my big toe on my operated leg, i asked my consultant about this n he told me it was nerve damage after getting out of hospital my pain becomes much worse. i went to my doctors who also told me it was nerve damage. one week later and im still in complete agony all together i have had this pain for 3 weeks . i then went back to my doctor again last week who confirmed my pain to be gout, he has prescribed me some medication called ARCOXIA otherwise known as ETORICOXIB i have been taking just 60mg of this medication for 3 days but they pain hasnt subsided. im not sure how long i will have gout for? has anybody else had gout for this long and is it normal?
