I have had Fibro for 30 of my 50 years, and it just never lets up for long. However, this past spring, at the end of May 2009, I noticed that I was not getting the calf cramps that are usually the first indication of a bad spell. I ride a bicycle "as much as possible", and I use that riding to gauge how I am doing. Usually I can ride for 20 minutes or so at a gentle pace, but last spring I was going further and further, being carefull not to overdo it and put myself back in the recliner for forced rest. At the end of May, I was working my way up to 15 kilometers - about an hour's ride, and not hurting like I expected. I added 2 kms. every few days and was tolerating it well - no calf cramps!! And over the summer, I worked my way up to riding 45 kms in 2.5 hours - Superman, and no cramps. I was in heaven all summer. What was different? I had changed my diet, which resulted in noticeably different bowel movements, and it seems that something to do with my gut was making it possible to ride more... but we never know of course. The warm weather also makes a huge difference for me [and most of us, right?]. The diet changes included more "probiotics" from Colostrum capsules, and plain raw milk yogurt [with NO thickeners added]. Also, lots of "oil seeds" - sunflower seeds, flaxseed, pumpkin seed, hemp seed and poppy seed [no drugs in any of those, by the way]. Coconut milk, berries, bananas and raw eggs [about 6 a day], and some, but not much, fresh veggies such as carrots, broccolli, and peas, plus a little bit of oatmeal, rounded out my diet. That is about all I ate, blended together [except for the veggies] with a bit of honey and lots of cinnamon. Morning noon and night I would make the milkshake with yogurt, raw eggs, and berries/fruit. Perhaps the yogurt was giving me calcium, and the probiotic "gut flora" was helping me use it? Calcium has something to do with muscle contractions, I can never remember if it contracts or releases them... and what is the other one - magnesium that does the other one? Sorry, brain fog... I know this stuff but I have to continuously re-learn it! Arrggg. Alas, this past week it all came back after a 30 km. bike ride - calf cramps and continuous pains there, general achyness, plus terrible fatigue and headaches. We are still having warm weather. There is less sunlight hours now too - so Vitamin D could be part of it, but I am still getting many hours of direct sunshine most days. That lasted one week, and by yesterday I was able to walk again without making the calves worse. Maybe I can ride the bike again in a few days... but the wonderfull summer of bike riding that hard is something I have not known for 30 years.
