<s>[INST] My chest fills like someone would be spitting on it..little needles sticking me..then it stops and my back starts hurting but it fills bruised now my upper right arm hurts..and sometimes I get light headed and have to take deep breaths like its hard to breathe.. [/INST] Hello dear, thanks for your question on Chat Doctor. In my opinion your symptoms are more suggestive of anxiety. But better to rule out cardiac cause first. So get done ECG and 2d echo to rule out cardiac cause. If both are normal then no need to worry about cardiac cause. Anxiety appears more in your case. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. Avoid stress and tension. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. </s>
