Consumer also stated, "Okay, I had my fourth covid Pfizer vaccine on 23May and I went to the pharmacy and when the pharmacist was giving it, I thought he was giving me injection way to hard, I mean, I thought it was going way to high at my shoulder. my lump is still numb and when I looked into the mirror I can see, I still feel the pinpoint where he gave me injection which is too far forward and way up in the shoulder joint and it is spreading into the, over the chest area. I don't have the ability to take pictures or computer knowledge, I could go to my daughter's home and have her taken picture of it. Alright I can, if you suggest going back to pharmacy and have then take a picture of it but I am concerned now my lump has gone completely gone numb now for five days. It looks like it hit the nerve in the joint or something numb, it looks like it was improper place where it hit vaccine. The lump just disappeared, but you see I mean it's very visible larger than the 50-cent piece, it goes towards my chest, you can still actually see the pinpoint of where they put injection in and it spread towards the chest area. It is way too high and way too towards the chest, I mean it is not in the deltoid muscle where it should be at all."

When asked for permission to probe, "Yeah I suppose, honestly think it is the matter of where the put the vaccine they put they vaccine and not the vaccine itself. I think I better go back to today and make a formal complaint about it." When again asked for permission to probe, consumer stated, "I guess, well I think my best part is to go down to the pharmacy and show him, but haven't taken a picture of it. Because I am concerned I don't know where I am going get to know this nerve back to this, some or not (incomplete sentence)."
