Thank you for sharing your experience. It is very interesting what you say about emotional and physical pain. They are very similar in nature from a neurological perspective and it is true that antidepressants can act as analgesics and bring about pain relief. Similarly painkillers can also have effects on relieving emotional pain. This suggests that on a physiological level there is something in common.
Lol totally get the martial arts thing. I think the teachers love to do stuff like that - I had very similar experiences. I think that as time goes on you learn to relax the antagonistic muscles.
You're right. Analgesics from antidepressants is a known fact, likewise the painkillers can have emotional relief as well. I took antidepressants after a car accident for the express purpose of relieving some physical pain without relying on pain meds. It worked.
Yes I had a friend who did his research project on it in University. They all have potent analgesic qualities:)
