Hi,
never underestimate an injury. Go to a doctor would be my advise....
One time, I gave a low kick and he blocked it with his knee, and my whole under part of the leg (shin, etc) did hurt and i wasnīt able to walk normal for 2 weeks. Thatīs the only (great) pain i had to manage so far... And yes I had to go to a doctor as well but I didnīt. I still have some pain on the same leg and perhaps when i did visit the doctor...no pain at all anymore..
Bye bye,
