PGP

It seems I might have what is known as Pelic Groin Pain (PGP), basically every movement we make our pelvis should lock to help us stay stable, with PGP this doesn't happen as it should, it is quite common during pregnancy but very painful. There are some days which I am in pain every second of the day and find it difficult to walk. Thankfully today is painful but not as painful as the last couple of days. I'm going to go to the doctors tomorrow and insist they refer me to a physiotherapist. I'm mainly worried about the fact that I'm getting such bad pain at 21 weeks, what is the pain going to be like when I get nearer to my due date, am I going to end up having to use a wheelchair, I might possible have to use crutches as it is.
