Alright, her doctor, she was seeing 2 doctors for this problem, one with heart doctor and one was lung doctor and when she went to hospital, she was walking and she collapsed, and somebody find her almost died or whatever,she didn't wanted to go to hospital but she collapsed again and then when they assisted that she need to get into the ambulance and go to the hospital, thank god she did. The doctor was figuring out what was going on with her, alright. He did test scan of her head right, there was no problem. They did one of her heart and it said her heart is slightly enlarged in one of side where as she had to go to the surgery, before they make a decision they did scan of her lung, both lung. she never smoked a day in her life before up the blood clot. Let her tell you something, the vaccine did to her.Right now, she didn't have history, her family didn't have a history to Pfizer vaccine, no problem. She was the one, alright she had to be hospitalized for about 2 to 3 days, they let her go and then she had to be on blood thinners so, she was supposed to be on blood thinners since last Oct and doctor made the decision to take her off, not take her off but to completely take her off but he says stop taking it for about a month or so. she went to (withheld), again almost died because the blood clot came back or whatever and she was told when she came back from (withheld) she was told and she went to the doctor and he did the blood work, the blood clot came back. she had to be on the blood thinners for the rest of life because of your vaccine, Apology is not accepted because you know what because she had 2 other people that she used to catch the bus with to go with because she was retired now, they died. They couldn't make to the hospital on time because the blood clot reach to their heart, they took Pfizer vaccine as well.They didn't make it but she did but she didn't think it was right and she will sue you guys because this is horrible, you know she had to be on expensive medications for the rest of her life and she was a healthy person, she was healthy and now she had to be on blood thinner Eliquis. Follow up: Consumer stated, "Yes, it is because she had a few things to say." she went to one of the best hospital and her doctor who perform surgery on her try to break out the clot in her lung, or whatever he is a heart doctor but her lung doctor at (withheld) association, he informed hours ago on last Thursday that he had to put her back on Eliquis and that she will be on rest of my life because of her since she was been off the Eliquis for about a month and could have died in and they were just seeing, make testing in her blood to give her break from Eliquis to see if blood clot comes back but it came back, doubled tripled. Consumer stated, "This was very first time, when she was in the hospital she found out, this is threat to her life ,she was going to die. There was not history of blood clot in family and for last 30 years that she had been going to doctor, her blood has been great. she was walker, walk like anywhere from 3 to 5 miles a day and that's day when she collapsed." Anatomical site: Consumer stated, "Okay, she was driving up so it had to be on her left side. she only had 2, she did not have any more because thing is that when she had the vaccine or whatever at that time you were coming up with third vaccine, and then 4th, she only had 2. First and second, she didn't have anything else." D-dimer has tripled like blood clot .she haven't had blackness, she felt like extremely tight, just like,she said that when she was elsewhere ,had to walk at pool park ,walk upstairs, she felt like she was going to faint and thing is that she was a person just like she told you, she can walk 3 to may be 6 miles a day or whatever depends how the weather is, she get up at 5:45 and walk in the morning time. So, for her to walk up to 5 stairs is nothing for her but when she was in, she had to go downstairs to go to main cafeteria to eat ,she couldn't make back up to stairs she was so exhausted like her heart beating out of her chest, having like heart attack that's why she had to use elevator or whatever to go back upstairs, she had to walk and she was off to Eliquis cause her doctors are trying to find out cause to keep the blood clot to come back and sure not that they did and that's what making her so tired.
