yeah, probably but not generally because of the cyst. Malignancy of a CYST in an area where malignancy about never starts off, is just bordering on totally impossible. So, cancer is not a realistic worry. Normal stuff is a worry. My aunt on my wife s side had a burst blood blister INSIDE of the spinal canal that caused all sorts of irritation. That is pretty rare. and, the only cysts I ever see in my patients are either from a congenital defect where the spine is falling apart (they would have mentioned that) or if there is mild to moderate arthritis with basically an internal blister. The blister isn t that much of an issue. Bigtime arthritis IS and is very common.
