<s>[INST] I have been to the doctor and they did an EKG and lung Xray.  All good there.  The reason they did these tests were because I have numbness/heaviness in my left arm/hand and tight chest pains near my heart.  I am now taking Prednisone but it's still there.  Any ideas?  Would it most likely be a pinched nerve?  Should I worry about a blood disease?  I am a healthy 32 year old woman.  5'10", 160 lbs. [/INST] Thanks for your question on Healthcare Magic. I can understand your concern. First of all, no need to worry for major heart or lung related diseases because your reports are normal. It is unlikely for pinched nerve to cause chest pain and arm pain together. In my opinion, at your age of 32 years, we should rule out vitamin B12 deficiency as a cause for this kind of pain. So get done vitamin B12 level and if deficiency then you will need supplements. If this is normal then stress and anxiety are likely cause for your symptoms. Undiagnosed, uncontrolled stress and anxiety can also cause similar symptoms. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on it's solution. You may need anxiolytic drugs too. Don't worry, you will be alright. Avoid stress and tension, be relax and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
