Is There A Link Between Fibromyalgia And Ehlers-Danlos Syndrome?

I ve had Fibromyalgia for about 3 years, but can remember when I was very young having the same symptons. I have severe depression, loss of memory and when I speak my words come out all wrong. I am currently taking Savella and Tramadol to help with the pain and depression. Do you think these are good medications? I am currently in therapy and also see a psychiatrist. Also, my sister who is in the medical field received some information on Ehlers-Danlos and a link to Fibrormyalgia. Do you have any information on this? I am 49, height 5 5 and weight 180. I am on several medications for depression and Fibromyalgia. With the Fibromyalgia I have gained about 40 pounds which is very upsetting to me. As far as my history, I explained above I have had Fibromyalgia symptons since I was 10 years old. At that time I was told by a doctor that it was growing pains. Now that I look back I think it had something to do with fibro. I had knee surgery about 10 years ago to align my patellas. When the surgery was performed the doctor found several little tumors. I was told it was synovial chondromatosis. I recently needed my knee drained and x-rays were taken. Again it showed tumors. I do not have any cartilage. I have extreme knee pain and told it was arthritis and nothing could be done except exercise. I also had oblation surgery a couple of years ago and that seemed to be the start of my depression. Doctors have said that would not cause depression. Anyway, that s a little bit about my medical history. My main reason for contacting you is to find out about Fibromyalgia and a link to Ehlers-Danlos. What can you tell me?
