Been told by the Dr there is no medication?

Hey, I'm 25 and was diagnosed with fibromyalgia in 2019 I've coped okay until now. I'm suffering with the worst flare up I've ever experienced I've been going home ill or not able to turn up to work. I nearly passed out on the toilet in work the other day. I went to the Dr's this morning and I was told there's nothing I can be given and after I said over the counter medication doesn't work they agreed it wouldn't however told me that's all I can do for the pain. Please can someone either help me understand this if this is true or enlighten me on what medication you're taking for it please? I need direction basically
