I suffer from daily neck and lower back pain. lately i notice i shake when doing things. my hands/arms shake when pushing against something. ?

See a neurologist: There could be many reasons for your hands/arms shaking from being deconditioned (i.e. out of shape) to your muscles spasming due to your severe pain which is trying to protect your painful areas of your neck and back. I recommend a face to face evaluation by a physician (such as a neurologist). They may need to send you for other tests such as MRIs if they deem your shaking due to true weakness
