I was involved in a biking accident yesterday on the road - driver ran a stop sign and hit my back tire, which knocked me to the ground. I landed on my knees, which are pretty badly bruised and sore. Went to the doctor and he didn't notice anything major - just wants me to keep my knees wrapped and iced. However, today I am feeling really tight in my lower and upper back as well as in my chest. Is this pretty normal? What other typical pains and such should I expect? How long are you usually sore for? I have to meet with the driver's insurace adjuster tomorrow and since I have no health insurance I don't know if I need to be looking ahead for injuries that might show up later. Are future injuries possible or would I know by now?
