When I fist experiencing fibromyalgia symptoms some years ago, it was difficult to diagnose so I kept being bounced from one doctor to another - at one point I just gave up after hearing that it could be depression or muscle spasm or what not - finally I got diagnosed and put on Lyrica -

Again fibromyalgia is related to mental/emotional wellbeing - I still suffer especially when stressed

Probably why I can relate to your post - I get it 💙
