Someone here who knows about horse riding? I've joined a horse riding club, and was taught how to post on my first day. I'm sill learning and my posting isn't half as good as it is supposed to be. I went to the club last thursday, then day before yesterday, and then yesterday. Today would be my 4th day. On my first day, i was fine. the next morning, after I wokeup, i had cramps in my back and upper legs (The part of the upper legs, where the thighs join with the pelvis). But it wasn't severe. When I rid day before yesterday, I was perfectly fine. That day I rid really good, and after I rid, I had a little tingling (nice) feeling in the same part, where the thighs joins with the pelvis. Next morning after I woke up, again the cramps were more. Then yesterday when I rid, things got bad. Riding wasn't good, I couldn't post properly because I had a really bad headache, lots of bumps, and then a backache. By the time I reached home, I had backache, but the pains was drowned by the pain in my thighs, and especially that same place where the thighs join with the pelivs. I good walk properly though, but the pain increased. Now today after I woke up, I can't even stand striaght, the cramps are really bad. I can''t walk properly either. Is this normal? I thought cramps come once and then don't come again unless there's a gap. Why am I getting cramps after every time I ride.
