You need to look for studies on PubMed.
But a few caveats about Tramadol -
Has the same risk of serotonin syndrome - so it would not be prescribed if you are on two anti-depressants. My daughter was only on one anti-depressant and her pain management doctor and rheumatologist were hesitant to put her on Tramadol. They did, and she was fine, but the two anti-depressants might be why your doc hasn't mentioned it.
It has side effects - if Flexeril caused side effects at 2.5 mg (which is a BABY dose), so will Tramadol, I would guess. Expect nausea, sleepiness, feeling "fuzzy." I remember you having slow gastric emptying - Tramadol can worsen that.
The good news is over time you get used to them but the bad news is over time you get tolerant to opioids and need higher and higher doses. That is why doctors are now not using them for chronic conditions as much as possible.
I think another reason might be the opioid epidemic - doctors are now VERY hesitant to prescribe opioids, even mild ones like Tramadol. They want you to try everything else first.
Things you could try:
Switching anti-depressants - some anti-depressants work well for pain, including Fibromyalgia pain. Cymbalta is one.
Trying an anti-convulsant (might be allowed even with antidepressants - my daughter takes Gabapentin with an anti-depressant).
Trying injections into the joints that hurt - steroid injections. So for example, if you are having lower back pain, they may do facet joint or SI joint injections.
Trying another NSAID - I would also about the more gut friendly NSAIDs. Advil is NOT one of them. My daughter (who has a very sensitive stomach!) can tolerate 3 - Mobic, Celebrex and Relafen. She does need a PPI with them, but they work very well for rheumatic conditions.
I'm not anti-Tramadol at all, in fact I am pro-Tramadol for occasional use! I think it works well and for MOST it has few side effects. My older daughter takes it occasionally. I just think, unfortunately, with the opioid epidemic, you may have a hard time getting someone to prescribe it
.
It is very frustrating to us too that patients who are responsible and really need pain relief are now suffering because it is getting harder and harder to get opioids. I have a daughter with very severe AS and significant joint damage and her quality of life would be a lot worse without them.
My younger daughter's rheumatologist told us at the first appt. that she NEVER prescribes opioids and you have to go to pain management for that. Often rheumatologists only take care of the disease - and they consider the pain that comes with it a pain management doctor's problem if it is not controlled by NSAIDs, DMARDs and biologics.
Another reason might be that you do not have a proper diagnosis yet, right? Currently they are just calling it a connective tissue disease which is vague. Your rheumatologist doesn't know what you have and until she does, she may be more hesitant to prescribe certain drugs. That is probably why she put you on Plaquenil - it works for some patients but it's a pretty mild drug. Probably the mildest DMARD she could have put you on.
The best treatment for fibromyalgia is actually exercise. There are plenty of studies that support that. I would try to get 30 minutes of aerobic exercise a day - it can make a huge difference. It doesn't have to be intense exercise - even walking counts.
Good luck!!
