Pain Is Moderate To Severe At Times And Is Primarily

pain is moderate to severe at times and is primarily in joints re: ankles (goes up the back side Achilles and causes burning sensation to occur) hard to walk, going down steps (harder than going up), right hand, fingers, wrist (more pain than L side) and is starting now to effect right elbow joint. Hard to grip anything. weakness is getting worst with each passing week. Unable to do certain exercise and tasks like I could 3 months ago. Left hip is also effected. When sitting down hard to lift my leg using hip flexor need to assist with my hand. No history of illness. post menopausal. 55 yr female. very active and normal weight for height.. No recent injuries. Just went to family doc and have ruled out RA, Lupus and lyme through blood test. I am getting afraid. Have been on statins for 6 yrs and took myself off of these 2 months ago thinking they may be attributing to increasing joint pains and loss of mobility I'm experiencing.
