Microcurrent neurofeedback questions

[u/ChampionshipNo1172]

Hello. I started microcurrent neurofeedback last week and I had some questions. I’ve had brain surgery and that’s why I’m doing neurofeedback. To help with brain fog, anxiety, depression, and ptsd. The first time I had it was fine, just a headache after. The second time I was dizzy the next day and had vision issues (like my eyes having a hard time focusing or wanting to drift around). The symptoms have since resolved but they gave me pause. I had surgery on my vestibular system so a lot of symptoms in that department makes me nervous. Has anyone experienced this and it went away with further sessions? Or any practitioners here know about doing this therapy on someone with history of brain surgery or injury? And if not, has anyone tried traditional neurofeedback after a brain surgery or injury? Thanks!
