I started Paleo in Jan and in the spring began lowering my medications. I now take half the Methotrexate and have gone from every 2 weeks to every 3 weeks on the Humira.
My Rheumatologist (who is older than dirt and quite old school) said "what ever you're doing keep doing, I consider you in remission". So meds gave me my life back and nutrition put me in remission!
Please have you BF encourage his cousin to find a Rheumy who is more open!! Feel free to share my story.
*Cranky*. Man it ticks me off when Rheumys won't look at nutrition
