<s>[INST] I am experiencing tingling and pin and needle feeling in my hands and arms. Thought I noticed it in my legs the other day? I am female, 47, overwieght (205pnds) ,5feet 8 inches. I drive a lot for my job, I do have horrible posture. I have liposis so there is a lump in the middle of my shoulderblades. I am eating healthy and trying to exercise more. Shaking and flexing my hand seems to help this numb feeling subside. I do not take any medication. My first thought was I was having a heart attack or stroke, but I am hoping it is carpal tunnel or a pinched nerve. [/INST] Hi and thank for the query,this requires a careful evaluation of specific aspects of the past medical history and a complete physical examination. The causes are numerous, and could range from simple vitamin deficiencies to complex ones like problems with nerves or nerve compression. A proper consultation with a neurologist for an examination, and appropriate laboratory and neurological investigations would be most welcome. Kind regards </s>
