I only get crampy occasionally these days, but when I do it's bad and radiates to my low back (I'm 34 and have had my P since I was 8, intensity changes every 6-7 years). For me, swimming or jogging helps a lot, as well as non-inverted pose yoga. I don't do step or kick box when I am bad off. For whatever reason, the product Premsyn works SUPER for me, knocks out the bloating, back pain, headache, the whole enchilada.
