About a month ago I started having panic attacks that felt like heart attacks. I went to the emergency room and was checked out and my heart is good. He said that I could be experiencing Pleurisy. The doctor released me with steroids and muscle relaxers which I have taken them all. I am still having problems. I am not having full blown panic attacks but some days I feel really good and feel like I am getting better. Some days my hands start feeling shaking and I feel light headed. I don t know if this is still being caused by Pleurisy or I have been misdiagnosed.
