That's an awful lot of drugs that you are taking. I have no idea about what you should and shouldn't be taking, but bear in mind that drugs are tested individually, so that what they do when combined with others is not known.
I heard someone say that the only difference between a drug and poison is the dose.

You can also be susceptible to rebound pain, when the drug itself causes the pains it is meant to stop. You become dependent on increasing doses and if you leave it too long you start to get withdrawals and the pain.
Quite subtle and you might find it hard to believe as the pain is real.
Might be time to get your medications all reviewed as they don't seem to be helping much. BUT... do any changes under medical guidance, as withdrawals can be nasty.

Seeing a physio is a good idea. While drugs only mask the problem and never cure, a physio is quite likely to be able to get to the root cause and get on the path to fixing it.

I use physio, chiro and massage. They all have a role to play.
My drug usage is now quite moderate, being primarily slow release paracetamol, topped up with tramadol as needed.

I also take magnesium chloride for my muscles.
Massage may help you sleep once the muscles knots are eased away. Works wonders for me. You'd be surprised at how much tension your muscles hold when you are in pain and not sleeping.

Good to see you are looking for alternative treatments. May take a while, but keep at it. Ask lots of questions and do research.

I wouldn't put a lot of faith in a fibro diagnosis either. Look for the real issues.
