I am 51. I cycled for pleasure & exercise before moving from the midwest to the PNW, riding every other day, about 80 miles/week. I got away from this when we moved to Seattle, mostly on account of the frequent rain. I've recently decided to get my bike out (Trek 7100 hybrid), and on my 6th ride, was up to 16 miles in about an hour. This was 5 days ago. The last mile or so of this ride however, I developed a sharp pain in my left butt cheek, from the pressure of the seat (a "Terry Liberator") directly where my pelvis presses against the seat (looked it up, I think it's called the "ischium"). The pain stopped immediately when I would stand on the pedals, and only really hurts when I sit on the bike, or press that particular spot. It really is quite sore. I bought a "Bell" seat cover with pads, like the one in the pic, it's quite supportive yet compliant, yet still, simply sitting on the seat is really painful. I wonder if anything other than time might help this. I really am anxious to resume riding. Thoughts? BTW, I am not overweight.
