Looking for suggestions

So it seams that my beautiful little baby boy is pressing on a nerve causing my but check to be in severe pain especially when I walk what are some things that I can do to ease the pain so I can still get a few more weeks of work in I am about 36 and a half weeks now and was not going to stop working for another 3weeks but my job involves a lot of walking I work at a daycare with 3 year olds and can't keep up with them without wanting to cry
