hi marissa, sorry to hear you're going through all this.
i'm in canada too, but i lucked out in the early days, had a long term overseas departure looming so they rushed my dx testing. when i was back from my trip (postponed - thank you travel insurance, whew!) and the pressure was off, i remember being asked by my neuro at one appt, did i need anything further? i said 'how about a follow-up mri?' and he said 'okay, brain only 3 months wait, brain and spine 6 months' (or something like that anyway). ick! but i chose the latter b/c i was going to be out of province for 4 mo anyway, and why take less info when you can get more
if you want to try something on your own while you wait to see a specialist, i have spent the last few years researching nutritional health management. for the heat sensitivity, pain, muscle spasms/tics, panic/anxiety, and familial tendency to fibro, these all point to magnesium deficits. the hip and spine bone pain point to vitamin d3, which is closely linked with magnesium status also. both extremely common nutritional issues that can manifest in many ways depending on the individual. both nutrients are also known to be lower in ms patients compared to controls. (although often still within the 'normal' range - that's a whole other subject though). if you have a doc that will order nutritional testing, and will give you the results, that's a good start. what province are you in? in ontario patients have to pay for 25(OH)vitamin d3 now (unless you qualify for one of the listed exceptions) - they delisted that particular test from the OHIP schedule of lab benefits in the last year or two.
if these ideas interest you you might like to read some of my 'signature' links below.
