"i have had chronic pain from nerve damage when i had a mastectomy 11 yrs ago. have been to many pain doctors, tried epilepsy medicines, antidepressants, and now i am taking tizanidine, lyrica, cymbalta and a wonderful compounded pain cream that is a lifesaver for me! it has lidocaine, ketoprofen, and cyclobenzaprine. mention to your pain doctor. i put a small dab on my arthritic knee too. my insurance covers it 90%. good luck to all with chronic pain!"
