I have a Dr. appointment on Tuesday to ensure that my Diabetes meds aren t affecting kidney functions (my urine as been darker than normal this last week). Also, this week, I ve experienced irregular heartbeat when standing and exerting. Attendant with the accelerated heart rate have been pressure (especially from the neck up), dizziness, labored breathing, and some pain in the hand/wrist areas of both hands. I know there are several possible causes, such as irregular heart disorder, and thought I d stop by to check some of the symptoms out. At rest, none of the symptoms manifest themselves, for the most part.
Hello! Welcome on Chat Doctor! Your symptoms could be related to orthostatic hypotension or postural tachycardia syn Chat Doctor.  But this does not explain the pressure and pain in your hands. For this reason, I would recommend consulting with your doctor for a physical exam and some tests
