This ARD & CAPPS sounds so scary. I am happy to meet you, Deep. I love to make new friends.
I have a list of pain issues but the one that sounds a little similar is the struggle I have with IBS (Irritable Bowel Syndrome). I know the pain that can come with the muscles cramping has made me feel as if I was going to pass-out before. Thankfully my doctor and I found a medication that keeps the pain and cramping at bay for the most part now.
Take care,
