Yehuda Tzvi,
I am really sorry to hear of the tremendous pain you are in right now. I can not offer you any medical advice since I am not learned in these subjects.
However, I can tell you that I know the MOST EFFECTIVE cure for any disease in the world- tried and tested with best results…
badadadadummm….
Tefilla!! I am not saying that you are not davening. All I am saying is that if you write with such helplessness, there is a great chance that yo do not FULLY believe that Hashem is more powerful than any doctor and is able to turn around your situation within minutes!!! Maybe the reason why you are left so helpless is because Hashem wants you to turn to Him with complete dependance and faith. If you tell Hashem, “Hashem, right now there is no medical way to get me out of this mess. However, I believe with complete faith that You are the One that gave me this nisyaon in the first place, and You are the Only One that can take it away. I know that since You are my loving Father, you only want whats best for me, and I trust that you will send me a yeshua now.” Then Hashem will surely hear your tefillos and answer you!Also, I would go to Gedolim for advice ( to see if there is any other option) or just for a bracha. I would also still make hishtadlus whenever possible, keeping in the mind that really only Hashem holds the key to your yeshua.
May you only see yeshuos and nechamos quickly!
