I have experienced severe muscle soreness, swelling, inflammation of muscle and just a month ago, 2 months which was a month after I got the booster (Further clarification unknown) I have developed DVT in my left leg and multiple embolism in my lungs otherwise prior to COVID shot I was in perfect health. You have the dates out of order, Jan and Feb I got the 1st 2 shots in my left shoulder, within a month I begin to get extreme weakness in my both shoulders, 6 month after having my 2nd shot, I had my booster in my right arm and within a month after that I begin to get even more muscle soreness and Nov which was just 2 month after I got the booster is when I was hospitalized (Details of hospitalization was not available over the call, hence hospitalization was not checked as seriousness criteria) with a blood clot in my leg and numerous embolism in my lungs and none of my blood work or CT scan or anything relate to any other illness. My husband is retired physician and 3 other physician that I saw when I was hospitalized, all short of leading toward having a relation to COVID shot so I am reporting the symptoms so that it will be on file. Well because I got this severe I ended up having to go to a rheumatologist and I had all kind of test and they have all been negative until I have blood clots and then of course and then I had the test that confirms the blood clots. I just want to report all this. I have a gentleman friend he is a friend of our family that experienced a blood clot behind his left knee just like I did after he had his booster and also pulmonary emboli so it make me kind (incomplete sentence), I had a cough, just a slight little cough nonproductive cough for couple month and I thought because I live in # that it might may be I have developed like an allergy from things that loom down here but the pulmonologist that saw me at hospital thinks that because I have so many blood clots in my lungs he thinks cough was associated with the fact that I was developing blood clots in my lungs it just didn't happen overnight it was happening from weeks may be couple of month."
