Been Having Pins And Needles In My Hands And Feet,

Question: Been having pins and needles in my hands and feet, with nerve type pain in my left shoulder that wakes me at night for a year now. I also have extreme bouts of vertigo/dizziness that cause nausea. If I lay down the session does ease. I get slight sensation changes in my big toes and sometimes the odd finger, with intense burning sensations in my feet and index finger. I have also started recently with severe knee pain that can last a few seconds to a few minutes. I have had 2 MRI scans and 2 CT scans. A cavernoma was discovered in my medulla. However I was informed this could not be causing my symptoms. (Although I do question this).. Recently I have been having trouble finishing sentences/conversations and finding some words, sensations have started in my lip and face with pins and needles in my right cheek that are there permanently with eye lid twitching. Little muscle twitching in my hands also especially both thumbs. If I use my hands for any awkward or difficult work, like putting in screws with a screw diver the fingers may spasm for a few minuets following. Over the past 2 days it has all got worse. I have felt dizzy, shaky (eventhough I am not shaking on the outside), I keep seeing little dots infront of my eyes and the worst symptom is intense buzzing / pins and needles feeling in my thumb, so bad at times I couldnt use it or the sensation would make me feel sick. I intend to make another appointment with my neurologist. But the medical profession to date, which has included at least 5 different GP's a consultant neurologist a consultant neuro surgeon and a consultant psychiatrist all tell me that its migraine related with some possible trigeminal neuralgia. I am a 46 year old male. To be honest I am at my wits end as I feel trapped in a body that no longer functions as normal.

I have had numerous blood tests and all have been normal so I don't believe its anaemia or a deficiency of any kind.

If it was the cavernoma, which i have been informed I have had from birth then why would it start to cause symptoms now? when the MRI and CT scans show that it has not had a bleed?

Can it cause symptoms without bleeding? as I have been informed the risk of bleeding is around 3% so I should not be concerned.

I have also been informed it is non operatable without significant risk to life
