Hi , I ve had a hysterectomy 5 weeks ago and within the last 2 weeks I ve had very bad pains in my knees to the point of not being able to get up or sit down, and having difficulty walking. My wrists and elbows burn so much that I can t raise a coffee cup. I ve also gained 15 lbs since my operation. Removal of cervix , uterus, Fallopian tubes , left ovary. I still have my right ovary.What can I do for the pain? How can I stop the weight gain?
