This sounds so familiar to how I was for several months pre-diagnosis. I was 'surviving' on 3-4 hours per night, but it was taking a massive toll on me. I was having terrible stress at the time from my employers (the job I could do fine and enjoyed), and all the med results told me my heart itself was fine but the stress was causing my muscles around my heart to spasm which caused the heart attack symptoms.
After diagnosis I was put on statins to reduce my cholesterol, but this caused immense pain in my legs (simvastin and atorvastin) from muscle wastage, so against my gp's advice I came off them, amended my diet with LCHF and increased my exercise, thus reducing my cholesterol that way. (And silencing my GP !) The meter given at diagnosis showed I was off the top of the scale, and had to be put onto insulin immediately as I was at a life-threatening level (so that bit's different to you), however my hba1c reduced rapidly and with improved conditions at work since diagnosis, those pains are now few and far between.
I was incredibly grateful to be diagnosed with D. I was so ill at the time I feared I may have cancer again (had it and beat it 30 years ago), and was worried I didn't have the strength to go though it all again. However, with the help of the medics/insulin/LCHF and exercise/and you fine folks (not forgetting family and friends), I'm now 'fitter' than I've been in years. I no longer need insulin thanks to LCHF. How permanent this is, time will tell, but am happy with BG results so far, currently being in the normal range.
For any muscle/joint pain now, I use Phorpain gel, which provides instant relief and allows that part of my body to relax which then sorts itself out. Initially I got it for some damaged/torn discs from an RTA 25+ years ago, but after checking with the docs, it is safe to use for me to use elsewhere. NB I can put it on my chest because I know 'what' that pain is in me - others need to check, as it won't mend a heart disfunction!
Codeine Phosphate 30g can dull the pain, but I can't drive while taking it so that's a no-no for me other than at night, so I tend to avoid it if at all possible.
