My 2nd pg (age 35) was like that. It was hell. This is what saved me.
2x a week chiropractic adjustments eliminated all discomfort and pain. Find someone local who is experienced with pg women and young families. See if 1x a week will do the trick.
Post on Peachhead yahoo group (great e-mail discussion list for LA Parents) and ask who is good.
The other thing that saved me was getting an NAET treatment.
It's a non-invasive, natural allergy elimination treatment.
I was taking LOTS of iron from my homebirth midwife, but it wasn't making one dent. I was freaking out because if my iron levels remained low, I couldn't have a homebirth.
It turned out I was allergic, thus deficient in iron. Nothing I was taking, no matter how good or pure it was, was getting through, because I was allergic to it! duh!
After one NAET treatment (on a Friday) I had a midwife check up on a Monday and my levels shot up and stayed up. I was good after that.
Find a local NAET person and get referrals from pg women and young families he or she has treated.
BTW, at my daughters 11 month check-up, her iron levels were very high (woo hoo!) which wasn't the case with my son 4 years earlier.
