Hi, Antoniette:
Swimming is best, especially if in minor flare but it is not safe to exercise when in severe flare ups.
Walking is good.
Jogging is not good.
Light weights over full extensions is good but power lifting is not good.
Get out of inflammation by doing the diet:
Diet is a 10
Exercise can be a 4
Drugs are a 2
You need 13 points to avoid severe long-term damage.
Please don't exercise through the pain; it is not a good idea no matter what your tolerances are and especially if you are using drugs to mask some of the pain--that obviously makes the ability to listen to your body much less effective.
Good luck,
John
