Thx for your comments. I do take Vit D and Calcium. I also deplete rapidly of magnesium, so take supplement as well. I do get depressed, but try to keep pushing. I do kayak and canoe racing as well as cycling. Sadly, these activities require hard seats ((even with cushioning) and sitting for prolonged periods. My sore inflamed.bottom would no doubt be better if I did something else, but my mental health is good when active.
