i have had ketamine like your daughter, and when I have a flare, I soak in dead sea salts, or epsom salts.... I dont know if it helps the flare itself. But it helps my muscles around it to relax... Also... i get a heat pack you heat up in the microwave and make it warm and put it over my eyes. The pressure on my eyes helps me relax... But the salts do help alot during flares.
