No - in fact I remember when I was younger and it was pretty bad, I would hobble to the barn and ride in order to 'cure' the pain and agony. After 8 fences, it was wonderful, a miracle cure, actually. Riding was/is the best cure for cramps and feeling awful, as some people run for the same kind of relief. Nothing like it. Horses are really the best thing in a girl's life. So no, no stopping competing or riding for a period.
