Thanks for your replies! I do think I've probably been too aggressive with stretching, and then it flares up. I will try gentler. I will definitely get more advice from my doctors on how I can try to treat the plantar fasciitis, and revisit an injection possibility, but it sure scares me. I've had PF before a couple of times, but it was mild and would go away after I stopped exercising for a few weeks. This is nothing like that, and the additional burning CRPS pain is totally different and much more painful. I had natural childbirth too, and you're right nothing compares to that pain! But at least you know it will be over at some point. Thanks again!
