Hi! For about five months now, I've been experiencing muscular pain in my legs and lower back. It's worst in the morning and on the bus ride to and from school (I'm 17, and female), and also after physical activity. Recently the pain has escalated, and when I walk up and down stairs I get a sharp pain in my knees.
I went to the doctor and they did several blood tests for rheumatoid arthritis because of a family history of it, but those came back negative.
I haven't injured myself that I know of, but about seven months ago I started Tae Kwon Do, and shortly after that schedule went from 1 hour once a week to 2-3 times a week for 2 1/2 hours, the pain started worsening.
I know the two are most likely related, but how and why? I'd like to continue doing TKD, but not if its going to cause pain like this. The doctor prescribed Naproxen for pain management, and told me not to do any strenuous activity. I go back in a month to see how things are then.
If there's anything I've left out, let me know and I'll put it up, I'm very new to all this!
Thank you for your time.
