Refuah shelaima. I’m sorry to hear of your difficulty.
Please remind us of your mother’s name.
I don’t mean to sound preachy, and it could very well be that you did this already, but maybe your mezuzos and/or tefilin could use a checking?
I think that the above posters made good points. Maybe it’s a tikun, and maybe it’s an idea to consult with another specialist. Have you consulted with the Skverer Rebbe, who is an expert at directing people to proper doctors? 718 436 9595
May you have a refuah shelaima bekarov bimhaira besoch she’ar cholai Yisroel, and may you see the yeshua very soon.
