Hi spk676,
I would suggest making an appointment with your family doctor. Telling
your doctor the types of things you are experiencing. Your doctor will
no doubt examine you and he or she will do what's necessary.
Maybe you do need an x-ray, but you need a referral for an xoray from
your doctor. If you are still experiencing pain after 2 weeks, I would make
a doctor's appointment and let the doctor examine you. Better safe then
sorry as the expression goes. Falls can be quite tricky depending how
you fall. If the pain is there pretty much all the time, to me that's a sign
that you need to be seen by your family doctor. Also the fact that you
fell on a concrete fall with a football. Falls can be quite traumatic and
dangerous depending on where you fell and on what part of your body
you fell on. I hope you get relief from your pain soon.
It probably is something musculoskeletal. It would be too weird for you to suddenly start having heart problems at the the exact instant that you fell. Also, heart pain doesn't make it hurt to breath, but a broken rib can produce the exact symptoms you are having. You could have broken two or three ribs, for all you know.
If you did crack or break something, I don't think it's unusual that you would still be in pain two weeks later. I do think it is advisable, even at this late date, to go ahead and get an x-ray. A least you will know for sure what is wrong, and you can get a doctor's advice on how to deal with it. I think they still tape broken ribs. After the doctor examines you and looks at an x-ray, he or she should be able to tell you what to do and what to expect.
At 55 (and I say this at age 59 myself), perhaps your best football-playing days are behind you. No more playing on concrete, for sure. Congratulations on saving your grandson's skull, though. You may have kept a three year-old from having a concussion. That's better than a touchdown in the Super Bowl.
Let us know what you find out from the doctor, if you don't mind.
