There are many causes for this anywhere from muscle sprain/strain to heart problems to lung problems. Best would be to talkt to a doctor about it.
It could just be pleurisy pain which is a membrane around your lungs. It can inflame and cause pain
Yea that is definately what it is!!! I should go to the Doctor about it, hopefully they should recommend me some medication?
Please let us know what the doctor says. Don't let this go too much longer either.
Take care and God bless.
