I used to get that type of pain in my shins a lot. Ouch! For a while I had to stop walking. I don't know what it is, but I probably have lack of blood flow to my lower legs also. It has gotten better lately, I don't know why.
Now the pain seems to have migrated to my calf muscles.
Interesting you said this. That's one reason I was wondering if it was Bart. I had this a lot when I was younger but haven't had it in a long time, and all of a sudden I had it again. I backed off a good bit from my bart treatment a few weeks ago. I felt better (not herxing) until a couple days ago when I started having intestinal pain again. Then I noticed tightness across my upper ribs and soreness in the upper left quad of my chest like I had 3 years ago when my symptoms were at the worst.
I had diarrhea and vomiting a few weeks ago and then diarrhea again 4 days later. Weird looking stuff came out. After the 2nd time, my gut felt better than it had in a very long time (months to a year). Then I started eating bad food again (not that I ever stopped completely) and was craving sweets. Maybe it was candida that came out with the diarrhea/vomiting and bad food just restarted it. Candida antibody test I just had done was negative again.
So hard to tell. All I know is for the past 3 days I'm feeling worse again. Today I'm back to feeling overwhelmed, crying, anger, wanting to die because I can't handle stress at all, and wanting to run away and do anything that will distract me from the stress and misery.
