Help please!

Boyfriend hurt his back, we think it’s muscle pain. Its to the left of his tailbone. Its so bad he can hardly walk or stand without help and just moving or rolling over in bed is horrible. I’ve never seen him cry before but this is breaking him down and he can’t work because of it, he’s a carpenter.

We’re taking him to the doctor obviously but is there anything to relieve the pain until then? Other than pain meds obviously.

Help is appreciated!
