What Causes Terrible Pain In Fingers, Arms And Legs?

Hi Dr. Andrew, I am having terrible pains in my fingers, arms, legs & toes. the pain is so bad there are times all I can do is cry because I have had so many test done & sill no answers.. Just taking pill after pill after pill for not even knowing the reason I am taking them for... This is very scary & the chronic pain even takes over my daily function on times.... even the weather outside plays a factor in the strength of my pain. And on scale from 1 -10 when there is bad weather such as rain or snow I am crazy in pain.. Is there anything you can tell me about what s going on with me? Thank you for taking the time to read my complaint....
