Additional information: Reporter on the other line who was reporting side effects that were experienced after he had the booster shot of the COVID 19 vaccine. He had muscle pain and joint pain. Reporter says that what was provided by the transfer agent was almost right. What happened was that he had his 1st and 2nd dose and he had no problems. He had his 3rd dose and then about 3 week later he noticed slightly more muscle and joint pains that have continued to get worse and worse. Now, at times, it was hard for him to climb stairs or walk around. It was noticeable after no less than 2 weeks after the injection and it was there, for sure, by the third week. He wasn't really monitoring for symptoms because he had no trouble with the other 2 doses other than the average things that most other people have so he was not looking for anything. If his memory serves him right it was after 2 weeks but before 3 weeks for sure that he started noticing this. He confirms that these began sometime during Feb2022. He still has had it from that time and it is getting worse. He really was in tip-top shape before, he was walking or running 4-5-6 miles a day and had no problems. He is not the typical senior citizen at all, really. So what he has experience never fit in with his health and because of that he knew that something was up but he wasn't sure what it was. He had an x-ray of his back because the provider thought that it may be that, but it really wasn't. He finally put 2 and 2 together and this is the only thing. He was speaking to a nurse who said that she had a few other people mention that they had the same symptoms after they got the 3rd vaccine. Because of that he figured that his hunch was probably right, it had to be this vaccine. He hope he has answered this agent's question, maybe he provided a little bit more. The joint pain and muscle pain has gotten progressively worse and he is hoping that it won't get much worse. He has been taking Tylenol for it but he doesn't believe in many medication, like pain killers. He has just been fighting this off with Tylenol and sheer determination. Therapy start date populated as the date for the reporters first COVID vaccine and the therapy stop date populated as the date for the caller's third COVID vaccine. He had no arthritis or any of that. The only other thing that he had was a cholesterol problem and he takes a medication for that. Because of the cholesterol problem he has one stent in him but he has never had a heart attack and he was in good shape other than his cholesterol problem and he has had that for many years. He was on Lipitor for that but now he was on something else and had been for a number of years. He declined to complete a report on the patients who had the same side effects he had as was mentioned to him previously by a nurse. His doctor offered give steroids but like he said he was very skeptical with taking medications. He took him an awful long time to consider taking the 1st dose of the COVID vaccine and he was really against the 3rd dose. But he turned down the steroids his doctor offered because, again, it was not in his DNA to take lots of drugs. Reporter queried for what can he do to alleviate this on going problem. It had really changed his lifestyle. He was able to go on 4 to 5 miles a day jogs or walks and now that was very difficult for him. He would like to have some answers on how to bring himself as close to normalcy as he can. He declined to speak with that department because he says that they are going to reiterate his side effects and not give options as far as what to do to treat his side effects so it would not be productive as far as what he needs. Reporter queried for Now that this agent had all of this information what was this company going to do next. Will there be any follow up from one of the physicians or whoever might had a concrete answer on what he should do for this. To him it sounds like most providers don't had information on this part of the problem, which was sketchy. He doesn't look forward to obtaining information from them. Like everything else. there was lot of information out there, from what he had seen and heard, and no one knows much about this. He was kind of in a place that he doesn't like being because he doesn't know how to find answers to get out of this mess and get as close to normalcy as he can. He appreciates what this agent was doing but it hasn't been helpful and he just doesn't know where to go from here. Reporter wanted to speak to a department that would be able to give him a treatment response thing or speak to a doctor or a health care professional about this. Reporter stated that it was quite a disappointment. Not this agent personally, but the company as a whole. He adds that this agent seems like a very nice girl. He says he had a follow up number that the previous gentleman gave him but he could hardly understand him. No follow-up attempts are possible. No further information is expected.
