My heart rate is suddenly speeding up, making the veins in my left hand and arm visibly pulse. After a short period of time, the pulsing will slow back down to a normal heart beat, before starting up again later. It has become painful to fully extend my left arm, and my left hand/arm has gone tingly, with a decreased sense of proprioception in it. What should I do?
Age, diabetic, any neck pain, or trauma to neck. Its look like neurological problems, probably nerve must be compressed somewhere. So its need to be evaluated. First get chest and cervical spine x-ray done. If it suggests some we may ct or MRI. Till than you can nerve vitamin like erosion forte once a day and ask your local doctor for pregabalin. Also get yourself examined from local doctor for obvious finding.
