I've been in hospital for a small procedure which left me with lots of trapped wind. I've been home for 2 days, turned over In bed this afternoon and did a completely silent but REALLY long burp which felt like it deflated my whole body and all the pain in my upper back and shoulders just went. It felt so relieving and satisfying.
My sister once pulled a hair from her foot only to find it was really long and had somehow wound over and under every toe and when she pulled it , she felt it on each one.
