I used to have tons of neck pain when I slept on my side but a few months ago I got a cervical support pillow and I'm never going back, it's been a total game changer. I still flip between my back and sides but it's the best for both! Don't know what I'm going to do for a pregnancy pillow to keep me on mt side though, maybe one of those wedges. My friend let me borrow her u shaped one for a few nights but it was a disaster for my neck.
This is the pillow I got https://www.amazon.ca/dp/B07SHC9FG3/ref=cm_sw_r_cp_apa_glt_i_QKNDZEGX4CY6ZH9B8KW3?_encoding=UTF8&psc=1
I'm a stomach sleeper and sleeping on my back sucks, but it does help with TMJ, Have you tried cervical pillow? My neck muscles are often too tense and painful and I can find it totally uncomfortable, but have stuck with it for a few months now, and I wake up on my side only 20% of time now. Progress!
This contour pillow was interesting but it limited my movement when sleeping and was a bit uncomfortable because of that. If you do not toss and turn like I do, it could be worth a try and it looks like they have a sale going. Contour Pillow
So first, case I get in trouble here, this is just what works for me so ‘your mileage may vary’.
I currently have this one and it works pretty well for me. I mainly side sleep and I have found it quite comfortable for that. Before I just stacked pillows and none of them ever were the right height and that just broke the camels back and I partially herniated 2 discs and pinched. I’m guessing a lot of these memory foam cervical pillows are the same, I don’t know. https://www.amazon.com/dp/B07SHC9FG3/
Once my neck starts feeling like it’s on a stick, I’m pretty much going to have to lay down for at least an hour and take the pressure off. I’ll try and do sets of chin tucks without and with head turns while laying down. I normally won’t take NSAIDS unless it’s extremely bad also because of medication. Talk to your PT first, cause your condition is different from mine even though the pain seems to be the same/similar.
I only tried this one so far. Just ordered a differently shaped one (https://www.amazon.ca/Misiki-Cervical-Orthopedic-Shoulder-Ergonomic/dp/B07WYY8ML7), and can report back when I try it.
My main complaint is they feel too hard, even tho they are pretty soft when you touch them. It's mostly due to all my shoulder and neck muscles being so messed up, because my bf (who doesn't have those issues) finds it very comfortable.
I highly recommend this one.

Amazon tells me I ordered it over 2 years ago which is the longest I've lasted with any pillow. It worked great at first but now I'm less in love with it. Not sure wha the change is/was but it happened in the last 6 months. Might be me, might be the pillow. I find it too hard when I actually have a migraine and use something much softer (something akin to those super soft squishable stuffed animal-type pillows).
I was a stomach sleeper and that can mess up your neck including SCM muscle. There is a ton of stuff out there that people try and different things work for different people. Some things I would recommend you try and see if they help:
I hope you feel better soon. Keep in touch with us here, if you need support or just want to share. It's terrible feeling alone with something people around you can't easily understand, but we are here. :)
