Hi Smoochie!
I'm so sorry you're miserable...both emotionally and physically. May I add a few ideas to Char's great comments?
First...you need to find some way to relax! Warm baths, quiet reading time, someone to hold your hand or watching a beautiful movie. I don't know what would do it for you but stress and worry will definately increase your pain. Ya, ya...I know what you're thinking. "She has NO idea and it's easy to TELL me to relax but I just can't!" Been there

I've lived with pain that didn't seem to have any cause nor relief and medical problems and had no insurance so I can sort of get your feelings.
I am not a doctor either and can not diagnose you, of course, but I will share my experience. It's all I have and you are welcome to it. Take what you like and let the rest go...OK? about
insurance... there are options for people who can not afford insurance. One is state sponsored insurance. Here's a link to help in your state.

If you can't find help this way then call your local Red Cross. Yep, they'll help at times like these. Your health IS an emergency and they will find what is available for you. Here's a link to your local Red Cross.

There are lots of places to get help with free medications. Just use your Google or whatever you have and do a search. Plus most drug companies offer free or reduced cost pills for those in need.
And one last thing...I wouldn't eliminate fibromyalgia as a possible cause just because Lyrica didn't work. It doesn't work on about
1/2 the people who try it. Did nothing for me but make me sick. Fibro is a horrid disorder that not only mimics other diseases but no one treatment works for most everyone. Plus the majority of doctors have no idea how to treat or diagnose it. When you get back on coverage again I would think you could benefit from seeing a rheumatologist. They are usually the ones to confirm the diagnosis.
Sorry this got so long...sometimes I just get carried away...

I pray you find some relief and remember when you get stressed out that Chutzie has her hand on your shoulder. And she's whispering in your ear..."relax Smoochie, sit and find something soothing to do, get yourself a nice beverage, look at that sweet little girl smile and giggle and enjoy the love of your dogs"
Then wait for that handsome hubby to come home and put his arms around you. That always makes me feel better.
Hugs,
Chutzie
