Suggest Treatment For Pain In Hands And Arms

Hi! for 6+ months now I have developed horrible pain in my hands and arms. When I wake in the morning I am unable to uncurle my hand which are in loose fists. I try to pry my hand open and the pain is too intense (definately a 10). I feel the pain worse in the palms. When I force them open the muscles in my hands and arms jolt whith a higher level of pain and it makes me nauseus. The joints and knuckles and elbows are very painful. The pain has spread it used to be localized in the hands then it kept spreading up my arms. now it reaches my shoulder blades. Sometimes the pain comes and goes and sometimes it is more on than off. Lasting all day long. The pain also waxes and wains in intensity.Often my hands feel as if they are vibrating. I can feel the slightest touch in my hands & arms and shoulders so they are not numb. Sometimes lightly running my nails on the palm of my hand causes the vibration sensation to begin. Massaging the muscles in the affected areas feels really good. But as soon as the massage stops so does the relief. Please advise. :-) Thanks.
