Hi and welcome,
In the same way your attributing your improved function to your combined medications, it's possible that some or all of your symptom progression is interrelated to these medications too, eg Bupavacine
"Bupivacaine is a local anesthetic that is similar to lidocaine and mepivacaine (amide type). Bupivacaine, like other local anesthetics reduces the flow of sodium in and out of nerves. This decreases the initiation and transfer of nerve signals in the area in which the drug is applied. This blockage leads first to a loss of sensation of pain, then temperature, touch, deep pressure, and muscle control............
Bupivacaine (Marcaine; Sensorcaine) is a local or regional anesthetic used for surgical, dental, diagnostic, or obstetrical procedures. Side effects, drug interactions, and pregnancy safety information should be reviewed prior to using this medication."

[btw whilst all the situations are not mentioned in the above, it's also commonly prescribed for nerve pain (neuralgia), muscle and joint pain, fibromyalgia and to improve mobility]
You mentioned "Burning tingling in my feet (this is how it started) " and burning and tingling in the feet is most commonly related with the peripheral nervous system so if this is specifically your starting point the following may be relevant...
"While fatigue or a skin infection can cause temporarily burning or inflamed feet, burning feet are most often a sign of nerve damage (peripheral neuropathy). Nerve damage has many different causes, including diabetes, chronic alcohol use, exposure to certain toxins, certain B vitamin deficiencies or HIV infection.
Possible causes of burning feet:
Alcohol use disorder
Athlete's foot
Charcot-Marie-Tooth disease (a group of hereditary disorders that affects the nerves in your arms and legs)
Chemotherapy
Chronic kidney disease
Complex regional pain syndrome (chronic pain due to a dysfunctional nervous system)
Diabetic neuropathy (nerve damage caused by diabetes)
HIV/AIDS
Hypothyroidism (underactive thyroid)
Tarsal tunnel syndrome
Vitamin deficiency anemia"

In regards to an MS potential, a neurological condition like MS is highly unlikely IF all your neurological related test evidence has been consistently normal, not suggestive-consistent with spinal cord lesion(s) etc, which is quite likely why you've been dx with Fibro and nothing has shown up on your spinal MRI's. If an abnormality in your test evidence has been identified, any objective evidence would be your biggest clue on what medical conditions could be what's going on and at least give you some alternative conditions to be investigated for cause.
Hope that helps......JJ
Hello, I just wanted to say that I am so sorry that you are going through this. I have had a similar experience and am becoming more mobile after having to walk with a cane in March. It was really unexpected, having a lot of tingling and burning in right leg and can't figure out why it still has delayed movement. I also wear an eye patch for spasms of accommodation (When I look ahead, my eyes cross and see constant double vision. Before this, I just had blurry vision). However, all of my MRIs and spinal tap have been normal. I have just been on clorazepate and my walking gait has changed, so am unable to walk for longer distances without leg getting really worn out and feeling weird.
I wish I could provide an answer for you but do not know, as doctors have told me so far that stress alone has caused my symptoms. Just wanted to reach out and say that I wish you the very best and am so sorry you are in this situation!
Hoping you will soon find answers and long-term relief.
Not a doc, but if you (or Musicpiano below) live in a small town or rural county, find an MD outside your area. Write down these symptoms and note that they go beyond what is diagnosed as fibromyalgia. Also ask about the advisability if your current medications. Even if you get a chronic fatigue diagnosis, remain open to the possibility that you may remain undiagnosed and continue to keep your doctors apprised of your symptoms. It may be youdon’t have MS, but the lack of lesions don’t necessarily rule that out of 1 in 20 or even 10 later diagnosed have no lesions. MRI results even for followup are being called into question by a few brave medical rebels.
