About 2 Weeks Ago, I Was Prescribed 3000 Mg Of

About 2 weeks ago, I was prescribed 3000 mg of xeloda per day, 1500mg each time with 12 hrs gap. After taking this 3000mg/day dosage for 2 weeks (with 1 week on, 1 week off cycle), I stated getting acute pain in my right lower groin area, which then in few days became so acute that I have become wheel chair bound. I need to know if anyone else taking xeloda have experienced this kind of severe side effect of xeloda? If so, did he/she recover from such debilitating groin pain and how soon?
