<s>[INST] My left arm has been hurting all day I woke up to it and I can t lay on it or it hurts really bad. It s hurting mostly my lower arm and hurts bad in between my elbow. My hand hurts every now and again but my arm is throbbing and very painful... It s not swollen but it s almost had me in tears... What could this be? [/INST] hi you have throbbing pain in your (L) hand , elbow and lower arm . I think it is due to pressure on one the nerves in your neck which is radiating to elbow and hands . I would recommend Pain killers , pregabalin , Neck Exercises for 7 days and if there is no improvement then I would go For X Ray cervical spine AP/Lat </s>
