Left arm numbness 4 5 mnths. Er visit cbc, cmp, tropononin 1 and ekg, vascular screen all normal. Visit to orthopedic doc. Nothing abnormal in x-ray. Heart?

Very unlikely. It's an atypical presentation and the prevalence of disease in your age group is low. "common things happen commonly" - i'd look to your shoulder for the probable cause.
LUE numbness. Some relatively common conditions which can cause one sided arm numbness such as entrapment neuropathy and cervical radiculoapthy will not be detected on the tests you've mentioned. You can see a neurologist for an exam and a nerve study and (s)he will determine if additional diagnostic testing such as a cervical spine MRI or brain MRI is indicated. Hope nothing serious and good luck.

Maybe Orthopedic. Consider your cervical spine, which is where the nerves for your arm leave the spinal cord. You could have a pinched nerve. Also consider animpingement in the shoulder. A cervical MRI would reveal any impingement in the neck; make sure you get a weight-bearing MRI (done seated rather than laying down). An EMG would help determine if impingement is in occurring in the neck or shoulder. Read more...

Possible. Could be a pinched nerve or nerve root as it exits your spinal canal or as it exits through your ribs. Worth getting checked out. A good exam by your doc or neurologist could confirm. You may need a nerve conduction test as well. Seek immediate care if you have weakness in the arm or hand. Read more...
