I am adding my comment to others on cymbalta, duloxetine. It gave me constipation close to a blockage. It made my thick hair fall out. It raised my blood pressure to heights I never experienced. Going off was very hard. Pain in body and mind are hard to bear. We are better off NOT taking these meds but being very careful to manage pain with as little drugs as possible............use hot water, hot rubs that do not smell much, ice, rest, showers, and more showers, and keep warm. Watch out for nightshades vegetables ( they are tomato, potato, egg plant, and pepper) , Keep weight down although this is very hard if you can't exercise! You can't eat much but if you eat good amounts of vegetables and less calories in bread, potatoes, rice, and wheat etc. It is possible to lose weight. It just takes time. Cut portions down a lot. Do what you can for exercise on good days. Don't over exercise if you have not been exercising or you get hurt.......start slow and keep steady at it.
