I have taken Diovan for several years - about a year ago I was put on the generic valstarsan - 40 mg morning 40 mg dinner time. Now I am experiencing pain in my upper leg and a burning pain above knees and also sciatica. The pain is quite painful and keeps me awake. I have viral cardiomypathy, diabeties, and scardosis (spelling, sorry). I have alot of issues with artificial sweetners, foods, farm raised fish, latose intolerant, and gluten issues (not severe). I don t know where to go from here. I had 2 knee replacements 10 years ago and went this past Thursday to the orthopedic doctor that did my surgery. I thought because I had a couple falls, I may have damaged them. Dr. took x-rays and said they look like the day he put them in - no signs of wear or tear and are aligned perfectly. Any suggestions?
