Welcome to the ehealthforum. I am glad to help you out. From your symptoms, the possibility of coronary artery disease needs to be ruled out in every chest/left arm pain. For the same, it makes sense to get an EKG,echocardiography,cardiac enzymes and stress EKG done.
If these tests are normal, then the possibility of an extra cervical rib causing the compression of the nerves coming out of the brachial plexus (bundle of nerves supplying the arm) needs to be looked into. For the same, an anteroposterior x-ray of the cervical spine is required.
Another possibility is a carpal tunnel syndrome in which thereâs a compression of the median nerve around the wrist and also a possibility of the ulnar nerve around the elbow. These can be confirmed by doing the nerve conduction velocity test and by clinical examination. Please do consult a physician for the same as it is not possible to diagnose online. I sincerely hope this information helps. Take care.
