<s>[INST] I have had quite severe pain in my left arm and I have had a scan and nothing was discovered but since leaving A&E I ve begun to have tingling in my hand and fingers and now there is slight numbness at the end of some of my fingers, any ideas what could be going on.. [/INST] hi Hope this msg finds u in good health. I have gone through your complaints and understand your concern. From your history u most likely are having radiculopathies nerve pain which might be due to nerve swelling or its compression in the neck. If not dine get a MRI of neck done to find out what's wrong. Nothing to worry about. Hope your question has been answered.  Feel free to consult me anytime, thanks.  Take care god bless </s>
