Sorry you are having such a difficult time; I am allergic to most oral pain meds, and I do use lg doses of ibuprofen. Don't overdo, keep in touch with your doctor, and drink plenty of water. Ibuprofen can damage your kidneys if you take too much and it can cause your stomach to bleed, so be aware and be careful. I take three or four at a time; it usually works best if I take it right before bed. Try propping your painful limb on something soft; chenille throw, super soft pillow, etc. Not sure if this helps, but good luck to you. Suz
