Patient sees a doctor for lot of conditions one was for shortness of breath and sleep apnea and sees a neurologist for Bph. The patient concomitant medications were not reported.

On 06Jun2021, after patient took the shot, probably around 11:30 in the morning, patient was same, soon after 5 min maybe more, patient got a sensation on the left side of his tongue 5-10 mins, then  kind of a weird taste came to his mouth, patient started to get a little dizzy, a little light headedness, weakness in his chest and both his arms, got shortness of breath but had been seeing a doctor for shortness of breath prior taking the Covid shot and had kind of reluctant of taking the shot but some other issues going on side,  patient decided to take it, a couple of hours after the shot, patient had a headache, had the diarrhea. Patient described the weird taste like having a penny in his mouth. Patient explained he consulted a doctor on that Monday (07Jun2021), who said she encountered patients who also had the sensation on their tongues following vaccination, and that it was normal. Today (08Jun2021) patient had feeling just a little bit of nausea and patient kind a feel like a little brain fog, it was just his head doesn't feel right, the major concern was says some things risks factors and some of them had severe reactions, patient had a reaction difficulty in breathing, dizziness and feel little bit weakness, patient kind of a felt like his throat was going to close and he won't say he had any difficulty in swallowing, but it was not normal. Patient developed symptoms which spooked and scared him. Patient did not have his lab test but was constantly going to patient had just had right heart catheter right two weeks ago, you know last for him, patient was supposed to take another lab test to conduct at the end of the month for cholesterol, but patient saw neurologist for kidney disease. Events did not improve, patient just had this brain fog you know. Patient had to call a doctor after he got home, they did not prescribe him anything, patient mean he did bunch of appointment with doctor with the phone as soon as he got home from taken a Covid shot he was little worried.

Patient stated he will not be able to consult his doctor before the vaccination appointment and was not able to get further assistance from a pharmacist. Patient repeated he does not know what to do about the second dose. Patient was kind of reluctant taking the next shot, if he was going to feel the something like this again, he don't want to, as he already had uneasy you know just had and patient did not had difficulty in breathing all of time this comes and go,  from the sentence he described it says on pamphlet that there was severe reaction to the shot and don't want to take the second shot and then end up in hospital because patient had more from it so his question was he was afraid to take the second shot. Patient don't had answer to that he means he would like to talk to somebody who can give him information kind of help me to relax little bit if it was normal and in in response it was responded that decision to receive the second dose for any other reason cannot be made by the company. Patient was referred to speak to his healthcare provider about the risks of the vaccine compared to the risks of potentially not being fully protected against COVID-19 infection, as healthcare provider knows his health situation and had access to information that can better help inform this decision. The outcome of brain fog was not recovered and outcome for other events was unknown.  Information about lot/batch number is requested.
