Thank you for the query.
If heart diseases, lungs diseases and abdominal diseases has been ruled out, most probable reason of such symptoms is rib nerves neuralgia
. Usually it gives sharp pain
which increases while breathing or moving the chest. This may be caused by nerves irritation due to compression by ribs, spine diseases or local inflammation. Stress
and magnesium deficiency
can aggravate this symptoms.
I suggest you to try treatment with Diclophenac 50 mg twice a day, Magnesium 400 mg once a day. Pool swimming should also be very helpful due to muscles relaxing.
Hope this will help.
