I developed Reynalds disease in my feet unrelated to anything else. I am not a smoker nor do I have diabetes, etc. This was twenty years ago before osteoporosis raised it's an ugly head. It is caused by microcirculation so my toes are usually purple and cold all the time. I wear socks in the summer. The toes are becoming malformed and I have had major surgery for hammertoe of twenty years that got worst and, yes, had pins in my toes. But, it was worth it.

I also have terrible trouble with toes, can't sleep with pain in feet, I didn't know it was caused from osteoporosis.

yes ! i have bunions and hammertoes and my feet are very painful.

To the previous replies. The toes are not "caused" by osteoporosis. It just happened approximately the same time. As I originally stated the discoloration is poor circulation "microcirculation" and the deformity is bone related. I did not mean to misinform anyone.

I also have reynards in my feet plus blocked arteries in legs which stops blood flow to feet which makes them doubly sore.
