There is a homeopathic remedy that is supposed to be safe in pregnancy and it's anti-inflammatory called Arnica. Try that. Also, I received chiropractic while preggy--I am 34 and just had #2 a year ago. Wish I had done it with #1! It's fabulous for a pregnant body and supposedly helps get the baby in the right position as well. Might even help the inflammation. Starting to regularly drink some 'safe for pregnancy' herbal teas could also help bring down your inflammation issue.

Also, do some foods you eat tend to cause you more inflammation that others? For me it's dairy although my body tolerates it more when I'm pregnant since you need so much protein and calories for baby.
