Sometimes I get cramps in my legs at night. You might know the kind, you stretch or move your leg a little bit and WHAM! it time for a painful awakening. I get the cramps in my calves or in my thighs right below the knee joint. Sometimes I can massage the cramp out and other times I need to get out of bed and walk it off. I have done my homework and I am not looking for medical advice. Knowing how we are I am sure I will get some anyway No doubt the cramps are related to cycling. My father had the same problem so maybe it is hereditary too. Bought some compression tight for wearing under my shorts when I cycle. Mostly to keep my white fish belly legs from getting sunburned in the summer. Turns out I like the compression on my legs when I ride. Now I wear them if I am going on a long ride. One day after a tough ride I decided to wear the tights to bed. That night I started getting a cramp in my calve but it just went away and never got the tight painful knot phase. I have been paying attention since then. The only nights that I get serious cramps that I have to walk off is when I am not wearing the tights. Has anyone else had this experience?
