RA 3 month flare

I got a flare from doing 10 chair squats 3 days in a row. It lasted 3 months. Normally my doc gives me a steroid pack but she didn't want to this time. She said to "ride it out" because I shouldn't be taking them. I've been taking them about 2-4x a year. So the flare lasted 3 months! Affected my whole life. Was she right? What do you all think? I was mad.
