Low platelet counts leads to excess bleeding. An aneurysm is a brain bleed. The jabs cause all this.
An aneurysm is a bulging of an artery wall caused by weakness in that wall. Aneurysms often occur in the aorta, brain, back of the knee, intestine, or spleen, but they can happen anywhere. Most often, they occur at an arterial junction point.
An aneurysm does not necessarily bleed. You do not have an understanding of the medical terminology you’re using, nor of what causes it, nor of what can cause it, nor of what effects it has.
