Doctors only know how to prescribe meds. There are things you can do yourself to help keep from having flares. Emotional stress causes flares. Set reasonable goals for yourself & don't try to be superwoman. If you don't get something done today, the world won't come to an end. You can finish tomorrow. If a boyfriend, husband or family member wants to argue with you or talk about something stressful, tell them you can't talk about it right now & walk away. Don't let other people upset you. When you've had a stressful day, make yourself a bubble bath, put on some slow, soft music and de-stress.
Physical stress is also the enemy of RA. Don't try to lift anything too heavy or do strenuous exercise. Stay active but pace yourself & don't overdue it. Get plenty of sleep & try to take a short nap in the afternoon.
Extreme temperatures can also cause flare ups. Cold weather in winter, cold water in swimming pools or the ocean. A few years ago, while on vacation, i went snorkeling in the ocean. Worst flare i had in several years. There are many different meds to treat RA, some may work for you, some may not. You can always try something else.
As far as diet goes, i haven't found any foods that make it better or worse. Just eat sensibly. vitamins can help fight the fatigue that comes with RA. As far as herbs & home remedies go, i haven't found any that help at all.

I was diagnosed in October of 2015, at the age of 75,(go figure), and started my medications in January of 2016. No relief for 10 months, until my doctor added Leflunomide to my regime of meds, and within days, my flares went away. I almost missed the pain I was so used to having. I have been in what my doctor calls "disease controlled", not remission. I have had no flares for over a year now. Yes, please keep on keeping on . Keep fighting for the right combination and do not stop until you achieve your goal.

You asked about the Leflunomide 10mg I take. I take that on a daily basis along with Hydroxychlor 200mg and folic acid. I take MTX weekly, 5 pills. I have no side affects. When I started MTX I could count on nausea and fatigue the second day, but that has gone away.

I was in remission for two years. It's real but illusive.

Unfortunately I have never been in remission at all for me it’s but a bleak hope that someday it will I’m looking at alternative medicine right now because my RA Medicine has been very rough on my body
