Flare up or ?? Need some advice please ..

Hi all. Need advice. Always get weary and discouraged
I've been on antibiotics , different combos for a yr and a half. Last year I was about 98% symptom free from late August til December then had a flare. All orig symptoms etc. Changed meDs in jan -added rifampin for possible Bart. Then after abt six wks same thing, symptom free til last wk! I have been happy and energetic. Started spin class five days a week. Ten days later I started getting leg symptoms flare ups again. Burning stinging shooting pains down legs inside thigh muscle sore and tightness like cramping not like exercise cramps. Popping in legs is back but mostly the electric shock pains and burning. Going on for ten days now. Any advice. ? Can it be a co? I have these great months and then BOOM! Really stinks. Could the exercise have reawakened something? I feel like this is the symptoms I started with... Llmd said don't stop exercise and ride it out. But it's hurts. Thanks kindly for any response. Or if ANYBODY had the same leg issues if love to hear about it!
Fondly.

No I don't believe so. I did start exercising like a nut out of the blue and thought I was over this disease so I'm wondering if I threw my body into shock! Your guess is as good as mine. Funny thing is most of what I feel I have felt before, but with more and worse symptoms .. I don't understand the disease sigh
