Thanks for your question on Chat Doctor. I can understand your concern. No need to worry much as your MRI and chest CT are normal. Sometimes stress and anxiety can cause similar symptoms like hot feeling in chest, sound behind eyes etc. So better to 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. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
