srlh

I'm 24 years old and for the last year (at least) my hands and feet are always cold...they almost never seem to be at a 'normal' temperature. My fingers have also been tingling and have had pins and needles and numbness. I saw a doctor (a hand/foot specialist) in April who took xrays and said that I had no signs of arthritis or anything else that he could see and he diagnosed me as having carpal tunnel syn. While that may have explained the hands it never explained my feet. And after using the braces he gave me I found little relief. Since then I have experienced joint pain (mostly knees, elbows, hip, and knuckles/fingers), hands and feet are still cold, and I have just general weakness off and on in my hands/arms and feet/legs. As a side note (don't know if these could all be connected or not) since the beginning of the summer I have started to have heartburn and mild reflux (never had either before in my life), also have noticed that my hair seems to be growing much much faster than it ever did before (legs, arms, etc..), and my skin suddenly has decided to go through the teenage phase (very mild) I never went through. Any ideas as to what could be going on and as to the type of doctor i should find for all this?
