Hi Alison, , have you got a travel pillow? I’ve found thats helped so much as I have something to take the pressure of holding my neck up. I’ve also got a batwing pillow which has the little bit at the bottom to support your back a bit more, using that along with a back rest, and so far I haven’t had a backache. I guess we are all different though and its unfortunately a case of trial and error to see what works best, I really hope the pain stops for you soon and just keep the end result in mind! xx
