When you go or a review, go prepared with any questions you want to ask written down on a pad, and if you don't undersatnd anything get them to repeat and put in the report they will send out to you. You shouldn't have to fight for healthcare it is a human right!

Have they identified it is a musculoskeletal/ nerve issue which is impacting your body?
Did they investigate if it could be rib subluxation/costovertebral joint dysfunction, intercostal neuralgia, thoracic radiculopathy, muscle strain/spasm (intercostal, oblique, erector spinae), myofascial pain syndrome? I'm not medically trained I studied sports therapy degree over a decade ago.

I'm just trying to get my head around 3 years with no diagnosis, it must be really frustrating! I could understand in 2013 it took 3 years for a diagnosis for me, but medicine and science has come along way since then.

After 3 years your immune system has become over sensitised and that could be the cause of the pain you are still experiencing. That's what happened to me after my car crash, it's been 13 years and because of my immune system being over sensitised, I wake up and go to sleep every day with chronic pain.

But I hear you, I have had to advocate for myself, I've read up on my conditions lumbarsacral and cervical radiculopathy, and always question the GP and my consultant as they have advised treatments that were not benefical to me, as I had read up to date research on what they were offering me.

In England our health care is free, I pay for acupuncture, massage and cupping treatments and have had acupuncture on the NHS and am waiting for some more treatments. Also, I have had two lots of hydro therapy which is physio in warm water and it really helped, felt sore afterwards but generally my body felt better. I don't know how I would cope having to pay for all of my healthcare, but my son has started a new job and is going to put me onto his work healthcare insurance which he will pay for.

Have you tried Epsom salts bath? Cheap and cheerful £4 a bag and pour in a cup into my bath with some lavendar essential oil, great anti flammatory and muscle relaxant. Magnesium oil massaged into you muscles as long as you don'e have a fish allergy.

Also, I don't know how you feel about guided meditation (if you are using it already) to help with relaxation and breathing techniques, that's what gets me through my worst pain flare up and muscle spasms and gentle isometric stretches

Take care

$1000?! That sounds like a ripoff. And, I am sure that it is not covered by insurance. I thought Mayo was concerned with helping people in pain not adding to their pain by deleting their bank account. Correct me if I am in error here.
