Starting physical in the next few weeks. I’ve been in so much pain after I had my baby four months ago. I had to call off work two days ago and can barely hold him although he’s about 20 ish pounds now. Went to the ob yesterday and they told me that physical therapy couldn’t hurt since they think that he just screwed up all of my muscles and said that I was pushing for a lot longer than I should’ve been.
