What could these symptoms be related too?

I am 25 years old, and the doctors in South Dakota are really difficult to work with. I have had the following symptoms for the last 7 years if not longer and they haven't gotten better only worse a little bit each year.

-Hands, fingers, joints, palms, arms elbows ect. get tired and weak when working with simple tools, writing, typing, anything repetitive.

-Burning sensation when working with what I listed above almost like an overheating kind of of thing I have to stop and let my parts cool down for a few seconds.

-Coldness makes my shins, hands arms, basically all my joints, hip joints ect ache painfully.

-Major fatigue and tiredness (where I cant stay awake) after doing the above tasks for longer than a half hour, or even just out of no where.

-Headaches when doing the above things listed.

-numbness easily when sitting in arms, legs, feet, buttocks, ect. sitting normally or just crossing my legs. nothing too crazy.

I cant get a doctor to listen to me, so I am brining this to Yahoo Answers I guess.

Thanks in Advance.
