Relevant laboratory tests and procedures are available in the appropriate section.  Additional information: She had other conditions. She had investigations. She had not administered other products. She has been having an issue since last Nov and they haven't been able to diagnose it as yet. She has a lot of severe pain in lower abdomen and trouble with digestion. It may mean nothing but she got the booster shot for COVID the day before on Holiday and that evening she started getting the severe pain and nausea and whatever. States she ended up spending on Holiday and the next two days she was in bed. Whether that has to do with shot, she has no idea. She started taking Paxlovid one full day and night dose so far. She got concerned with her digestive system and she has stage IV cancer and COPD. Her severe pain and abdomen with digestive system started before taking Paxlovid, and after receiving the COVID booster. She received her COVID booster on 24Nov2021. She weighed 165 lbs, which has dropped. She lost weight. Last time she went to the doctor it was 180 lbs. She's dropped 20 lbs, when she has these bouts she cannot eat since the COVID booster. It is spasmodic. If she eats normal food, she will get the bout it in day or two, lasting 3-4 days where she spends the day in the bathroom and also while going to the bathroom she is vomiting. If there is nothing there to vomit it is usually mucus and water. States she is not vomiting any bile whatsoever, she doesn't think her body is producing bile at this point. She sleeps most of the time when she has it because she has no energy to do anything else regardless other than to deal with the severe pain. Nobody can tell her what is going on.  Event Details: She didn't report at the time because she didn't think the shot did it. Severe pain in lower abdomen: States she had the shot on the 24th and it started late that day and she had it in the morning and it continued for 3-4 days. States it stops and it restarts if she tries to eat normally. If she lives on water, crackers, and soup it doesn't happen. When it does happen it's very severe. It comes and goes. If she starts feeling normal and eats a little bit of food, about a cup of vegetables, mashes potatoes and drinks plenty of water sometimes that works. States but if she goes along 2-3 days she is back in the same thing for another 3-4 days and she has been dealing with it since then. She was in bed all day on Holiday and next few days. Spends time in bathroom and vomiting: At the beginning of the bout she gets the very severe pain where she can't sit or stand or anything with pain. With the severe pain she tries to have bowel movements the vomiting begins, so she is doing both. Sometimes it brings up nothing, sometimes fluid. It comes from, the exertion is from her toes and she has a lot of back pain from the muscles. It is so hard to explain. It is hard to say when the back pain began because it's not top priority. She attributes it to when she started straining to vomit, she thinks her back muscles got effected. She has issues with her lower back anyway, any kind of straining or pressure is going to make it worse. It was taken care of when she had shots and basically eliminated it until this started it again. She believes it's the stress on her muscles. It is ongoing, she is at the end of a bout of it right now that has lessoned because she stopped eating. Overall it has worsened. Indication: Caller tested positive for COVID and with her breathing difficulties and all that goes with it, she called her pulmonologist because she doesn't have a primary care physician, and asked if she should be on something.as her oxygen levels had been dropping and staying around 96-95% and not seeming to come up too much, and she didn't know if COVID was affecting her lung.

Family Medical History Relevant to AE(s): She had a mastectomy, they did a deep flap reconstruction, what it does is they cut you hip to hip and take the muscle from the lower abdomen and some of the fat tissue and essentially move it up and form a breast. They are removing muscle tissue from lower abdomen. She does have scar tissue. She questioned whether that would be a factor. She had gall bladder removed as well. She's had tons of tests, results unknown. If Pfizer wants to call they can and she will dig it out. Her chest X-ray, her doctor at # can speak to Pfizer about it. The first time she contracted COVID and it was her grandson she's pretty sure because he tested positive Thursday, and she tested positive Saturday, which is when she took the test. Culture was performed. She just did a home test.
