I've had back ache for 2 weeks now (not from cycling). A week last Friday I saw physio. Last week pain moved from my thigh joint to one spot at the top of my leg near my groin. Absolutely kills when I get up, and I cannot stand straight. Sitting helps. As the day goes by it eases off, but not by much. I tried back pedalling on Friday and it didn't hurt. Would it be ok for me to cycle short distances?
