Clinical course: Caller mentioned that because of the vaccine he got kidney cancer and Alzheimer's he was suffering from right now. Back when he took the shot he ended up, they got it all on record. He was sent all this stuff. Hard to breathe, blood clots in blood, cramped up, manhood problems still haven't worked since then. His blood thickened up, joints in pain, lesions on kidney and found out it was cancer. This ended up renal carcinoma on kidneys. Had to go through computed tomography scans and ended up having, he forgets things now. Had all these problems, it's embarrassing working all hard your life to zero and about to lose everything . Pain and suffering about to die find out cancer and get over cancer stuff and joints, he can not remember stuff and joints start hurting. Top of head feels about to blow off and did scan on, he had so many computed tomography and Magnetic resonance imaging scans. Did scan on head and said he had brain shrinkage and saw neurologist and stuff. Told he had first stage Alzheimer's all this is coming back can say what they want but he was healthy and fine and could take care of himself until he took that last shot. It started happening after the last shot. Doctor said nah nah and now all these people are stepping up and Pfizer was all talk about straight up honest billions they make and do not think about people that happens to. Only reason why he took it would be. Has worked hard all his life, not no bum and now having to sign up at 50 years old, 53 years old, for social security and disability because of the medication and what it had done to him. On this report, they do not have the final about the neuro doctor. Has to take a bag full of medications. Some for brain treatments, caught Alzheimer's 1st stage, brain shrinkage and takes medication for that. And for headaches. Amazing all medications are coming from China. Had to take all this medication and deal with headache stuff. It really hurts him because he worked hard all his life and built what he had was just about to lose everything he worked his butt off for all these years. Could not get help from anyone.
