Thanks for writing in.
Most likely it might be a musculoskeletal pain
and nothing to worry about. You could try having analgesics like brufen
along with antacids. However , if the pain is severe in intensity or occurs again, please visit your physician immediately , who will be better able to assess your condition. Meanwhile, I suggest you relax , sign up for yoga
classes/ practise meditation
to help relieve you from your panic disorder.
Hope this helps.
Have a great day.
