What Causes Severe Body Ache?

I have been suffering from severe body pain for several months now. Every joint, shoulders, knees, hips and elbows. Along with muscular pain. I had seen a nuerologist , she had done a blood test for Rheumatoid Arthritis, and apparently checked certain spots on my body for pain, ruling out Fibromyalgia. The blood work came out normal. Now I m at a stand still. AZ has a shortage of Rheumatologist, even more so in Tucson, so I ve been unable to get in to see one. The only way I can function each day is with at least 1200 mg of Ibuprofen. This has been giving me major stomach issues. I take Lexapro and Adderall, a doctor gave me tramadol to help with the pain, the mixture of the meds, nearly killed me. Without anything for my pain, I literally can t walk bend use my arms, if I squat down, I cannot get up. Can you give me any feedback as to what is happening? I m also extremely tired!!! Thank you for any input, I surely would appreciate it. Charlene
