warm baths help me I'm going through the same problems I'm 7months now and the pains started at 6 months . Warm baths, heating pads, and I purchased a body pillow off Amazon for $60 the best investment lol it makes getting a good night sleep so much easier.
Warm showers help me. I also use heating and cooling pads on sore muscles. Increase your water intake and eat healthy foods. I also see a chiropractor on a weekly basis.
