Additional information: A little bit after the patient got the shot the patient came home and didn't say anything about it but the patient have had like a light headache, well instead of it going away it got really bad. Like the patient had a migraine headache so the patient took migraine medicine and it didn't even touch it. Usually when the patient took that within a couple of hours it was gone if the patient had a headache. But the patient had taken it twice already and still have a migraine and the next thing was on skin the patient got big huge red patches, like right now the patient had one and it was like a big red circle, kind of just like a big red circle on there. So, the patient had one on the bottom, it went away. The patient had one at top and it went away. The patient thought the patient was allergic to something. The patient had been allergic to this stuff. So, the patient was getting red patches everywhere and they were not only, you could see the red big huge patches but you couldn't touch it. It felt like the patient had lighter and you put it into the patient's skin, it burns really bad. The patient had another issue with that. The patient got up yesterday and went to take medicine, for the morning medicine and when the patient went to swallow it like the patient's throat would not swallow it, like it was numb and couldn't get the medicine to go down. So, the patient drank some water down and got a mirror to see what was going on. The patient didn't really need to do that because as soon as the patient opened mouth and the patient's tongue came out and could see everything that needed to be seen. In the middle of the patient's tongue, there was a large section that was blood red and then on the end of that, both sections on the ends, were totally white. Something was wrong with the patient's tongue. It tastes nothing, tongue was on fire, throat was like it was on fire. The patient had been trying to use the drops that normally use when the patient get a flu or something but nothing was working. The patient wanted to know how to get out with what the patient had got because the drug caused it and didn't know how to get rid of it and felt like it was just getting worse, it was burning more. The patient had the red crap on leg and blood pressure dropped. The person got the 3 Pfizer shots, it was a little over 3 weeks ago and that was due to the vaccine, the patient got it but the patient was having some side effects from it but they were not very good and hurts really bad. The patient have places that just come up on the patient's body like big patches, like really red. It was coming in huge patches above the patient's skin and while it was there it just burns and eventually it started fading and another one comes up. The patient didn't know what to do. So, the patient was trying to do that and left there with a migraine first but the patient get migraines sometimes so did not do nothing about it but have had this headache since the patient got shot and it would not go away. So, the patient had that and then had the red crap on leg. Then the patient woke up that day and felt something was wrong because the patient went to swallow something and it was like the patient's throat was numb and couldn't swallow it. The patient had to grab some water beside to actually get the medicine down that the patient was taking. It was like it just went blank like it has nothing to do. So, the patient got camera and turned the light on it to look into mouth and didn't even have to look to the back of mouth. When the patient stuck tongue out, there was one big red section in the middle and then on each side of the tongue it was white and it burns really bad and the patient couldn't take crap. Now, the patient's mouth and throat were on like fire right now. The patient's blood pressure dropped. The patient already had test done.  No follow-up attempts are possible. No further information is expected.
