Oh endo flares are the worst arent they. For me its that deep burning pelvic pain that suddenly ramps up, bloating that makes me look months pregnant, lower back ache, nausea and just this heavy exhausted feeling. Sometimes it lasts a few hours, sometimes a few days and it can knock you flat. Stress and overdoing it always seems to make it worse, and heat, rest and being gentle with myself helps a bit but never fully takes it away. What do your flares feel like, is it more pain or more fatigue for you?
