My left arm always feels a lot weaker than right and can get a numb feeling to it, I often feel sharp pains or cramps over left chest area and back. These sensations tend to be more present when feeling anxious. Could this be nerve related pains and weakness? I have had these symptoms a long time,I often fear it s heart related, I get shortness of breath that feels like my back is tight, I do not get shortness of breath while exercising
Thanks forehands for your question on Chat Doctor. I can understand your concern. No, I don't think these symptoms are nerve related. By your history and description, possibility of stress and anxiety related symptoms is more. But better to rule out heart diseases first because left sided chest and arm discomfort are commonly seen with heart diseases. So get done ECG and 2d echo first. If both these are normal then no need to worry about heart diseases. 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 its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
