I don't know if mine is PGP... haven't looked too much into it... but my hips hurt REALLY bad, as does my lower back. My DS is 2 now, so I mostly just don't carry him anywhere that I can avoid it. We hold hands. I've found that I can barely carry the extra 26ish pounds of him and still functionally manage to walk. When we're out and about, I put him in a shopping cart or a bring a stroller... helps to have something to hold me up while I walk, and keeps DS contained.
Tylenol is barely touching my aches and pains... but I'm still taking it to keep the edge off. Also, lots of sitting and resting whenever possible.
