Doctors says, my mom is suffering from bppv. It's quite threatening for all of us. She cannot even sit for 5-10 min. It's her 3rd episode. She's taking cinnarizine, betahistine, pcm, cefixime, b-complex, and all. Can we have a permanent treatment? Currently she's suffering from one and it's very challenging for her. Improvement is very slow, it's been 6 days as of now. Please give some valuable inputs as of now how to treat this episode? Thanks in advance.
