What can be the reason for pain in the left arm and numbness in the jaw?

Hello,

Welcome to icliniq.com.

I guess you do not have any chest pain or heaviness on exertion or at rest. The first possibility is you are experiencing cervical pain, which causes nerve compression leading to pain, tingling, numbness, and burning in the arm. Do you have any history of neck or neck pain, stiffness, or arm pain? Spinning also supports the cervical cause. The strange feeling in the upper or lower jaw can also occur with anxiety or cervical cause. If it is in the upper jaw, then unlikely to be related to the heart, and the lower jaw may or may not be due to the heart. However, to rule out the possibility of cardiac pain reliably, you should get one ECG (electrocardiogram) done from a local doctor and attach a report. Also, similar manifestations sometimes may occur with gastroesophageal reflux disease (GERD). So overall, it is likely a cervical cause, but considering the risk factors, it is better to get yourself evaluated with ECG and, if normal, then stress test as you have risk factors. You will need an X-ray of the cervical spine anteroposterior and a lateral view of the cervical. You can take Pregaba M (Methylcobalamin(750.0 Mcg + Pregabalin 75.0 Mg) for the pain. I hope this helps, and you can get back if you have any doubts. Regards.
