Body aches / neck aches leading to sleepless nights

Hi mummies, I'm currently 21 week pregnant and I've been having sleeping issues due to my neck pain. It's tough as I can only sleep on my left, and when I do that, my right neck / shoulder will hurt especially later in the night. My husband massaged my neck to relieve the pain but it keeps coming back. This has been going on for a few weeks and I'm losing sleep cause of this. I went to see my gynae and a nerve specialist, they can't really give any solutions to help other than taking panadol / muscle relaxant topical cream / pain killers (which I try not to take as it's not good for baby). I also just went to see a physiologist and she taught me to do some stretches and put hot pack on my neck and see if it can relieve the pain. I tried the pregnancy pillow too, but doesn't help. I'm currently sleeping on a Tempur memory foam pillow (supposedly one of the best pillows) but it doesn't really help too. Does anyone experience this before? If yes, do you mind sharing how you cope / relieve pain so you can have a better sleep? Would love to hear any advice from mummies with experience dealing with this.
