Hello Dr. Bassel,It was a nice and informative video...I am Mr.Indranath Mondal age 35 from Kolkata,India...I have been diagnosed with Cavernoma in my pons near the stem during 2016 when I was staying in Netherlands..As per the Dutch Neuro consultant ,it is very high risk to operate it due to its location...The problem I have right now is the tingling of left hand and left leg...I came back to India and also consulted Neuro surgeon here and the opinion from them is same..Do I have to bear this tingling for my whole life...Couple of medicine has been prescribed but so such relief... It would be great if you can share your suggestions and advice.. Apologies for writing so long. Thank You
