Caller stated she had the Pfizer COVID19 Vaccination shot at between 11 and 11:15am on 25Feb2021 in her Left arm. After getting the immunization, caller stated she went to the store and at that time, it started feeling tight in the bend of her arm, on the inside near the elbow. Caller stated at that time the pharmacist also noticed what he called bumps on her along with the swelling. Caller referred to them as knots. It was swollen lymph nodes or something. After taking the shot, on her arms and legs, there was fluid built up on the skin, kind of whiteish looking spots. It took a while for some of this to go away, it had been 4 weeks tomorrow. The swelling has gone down some, but it was still there. It feels like it was trying to get in the blood stream. Also, the vein in her arm, in the middle, was sticking up a little. she was wondering if this happens with the first, what will happen with the second dose. question asked if she get the dose for the second dose. She does want to report as this was kind of weird, she doesn't think the drug store reported this. She saw the doctor 2-3 weeks ago and she was swollen up pretty good. The doctor asked if they gave the shot there and the caller told her, it was giving in the shoulder, referring to the swelling under her arm. She had a couple pharmacist as her that too. She kept thinking it was going to get better, it will go down. This had been a weird experience. The caller explained that she went to 2 different stores after getting the shot, by the time she left the second store she reports that the where the bandage was it started feeling tight. It started to hurt a little bit. When she got home and took off her sweater off and she saw it, she thought my goodness. She went to the drug store that she got, and her son came and looked at it too. Then it got in both arms, it was given in the left arm. She guesses it got in her blood stream. She went back to the pharmacist that gave it to her and he took her in the back where she showed him the little white spots on her legs, but he didn't say anything. She says that people get excited about thing though. She got the shot at 11 or 11:15, she stayed the 15 minutes and felt ok. About a week later in that arm where he gave the shot, it got all red but not streaked, just red. A lot of time she had shots; the flu shot will do her that way sometimes. She confirms the tightness was at the bend of her arm on the inside. Caller described it as being the same side of your arm that the little finger is on. Caller stated that by the time she got home it was swollen to a pretty good size. That same evening about 6pm she went back down to the pharmacy where she got the shot to show the pharmacist; and at that time, it had white spots on her arms and around the left wrist as well. Caller stated when she woke up on 26Feb2021 her right arm had become swollen as well. Caller stated the swelling has gone down a bit but was still there and the knots feels like it had little ridges in it, makes the vein in the middle of your arm stick up a little. She stated that she went to her usual # today to get some medicine and showed her and the pharmacist the inside of her arm and her pharmacists asked if that's where they gave her the shot. Caller stated she told the pharmacist no but notes that this was not the first time someone has asked her if the affected area was the area where she received the shot. Caller clarified around this same time, she also noticed little spots of what appeared to be liquid under her skin on both her legs and wrists. The pharmacist told her it was something in her lymph nodes. She guesses the medicine going in her body after being put in that muscle. Caller stated they are cleared up now.
