Patient's medical history (including any illness at time of vaccination) was none. Family medical history relevant to events: caller states he don't think so, his father had high blood pressure and diabetes. Concomitant medication included ibuprofen taken for tooth disorder at 600 mg every 8-12 hours, taking it probably a week before receiving the vaccine. No prior vaccinations (within 4 weeks). No events following prior vaccinations. No additional vaccines administered on same date of the Pfizer Suspect. The patient experienced slight pain at left shoulder where the injection site was at on 30Mar2021, chills on 02Apr2021, fever on 02Apr2021, sweating on 02Apr2021, continued muscle pain on 03Apr2021, skin, hair was hurting, couldn't touch skin on 03Apr2021, muscular pain down to pelvis and knees aching on 03Apr2021, diarrhea on 03Apr2021, fatigue in 2021, headache in 2021, weakness and dizziness in 2021, sinus drainage in 2021, feels dehydrated in 2021.  The patient was calling to report some long term, severe side effects. He received the Pfizer covid-19 vaccine on 30Mar2021. He didn't have anything then muscle pain for the first two and a half days, no reaction until on Friday 02Apr2021 he had extreme chills, fever, sweating, then that continued on to be muscle pain, his skin and hair were hurting, couldn't touch skin through Sunday 04Apr2021. It dissipated into muscular and inner-skeletal pain. He had muscular pain down to pelvis and knees and things would start aching.  Now it was kind of letting up. It was the 4th day now and no one he knows who had gotten it had such a long term reaction to this. Clarified that he had slight pain at left shoulder where the injection site was at and that dissipated on Thursday 01Apr2021 and he had no pain anymore and no other side effects. On Friday 02Apr2021 afternoon when it went haywire and thought he may have to go to the hospital on Sunday 04Apr2021. He had diarrhea and almost had everything on the list except redness at the site injection. He also did not have swollen lymph nodes. He didn't think he needed to go to the hospital, he normally didn't get sick and hadn't been ill for years and this was why he wanted to report it because it seemed that it was pulling for along time. He had been sleeping and drinking a lot of liquids. Headache, joint pain, and diarrhea continued all the way through Monday 05Apr2021 and started to dissipate Monday evening. He had no nausea and vomiting. The muscular pain down to pelvis started Saturday 03Apr2021. His knee would ache and then that would stop and then his other knee would ache then stop. It was like it would transfer around lower part of body, and that dissipated late Monday 05Apr2021 night into Tuesday (06Apr2021). Now he had fatigue was tired and had sinus drainage. He felt dehydrated and couldn't seem to drink enough liquids to get the feeling of dry mouth out.  The diarrhea, fatigue and the sinus drainage was still continuing and the other symptoms seem to have dissipated. He still felt so fatigued and didn't feel the other symptoms are there. He hoped they didn't return. It had stayed the same for the diarrhea, fatigue and sinus drainage and he was still tired. Later added he did have weakness and dizziness, but assumed it was fever and chills. Caller states he did have weakness and dizziness and Saturday 03Apr2021 and Sunday 04Apr2021 were the worst two for all of the symptoms at the same time. It had dissipated as of Monday 05Apr2021 evening. Outcome of weakness and dizziness: Caller initially confirmed it had dissipated as of Monday 05Apr2021. However, he later stated he was still experiencing slightness there. He still feels some weakness, and feels about 60% right now.  He thought it would be a good idea to get vaccinated because he had family members that had contracted covid-19 and be less weary of the virus. He was hesitant now to get the second shot. He was taking ibuprofen because he had issues with a tooth. He was taking Benadryl for the sinus and hadn't taken it in 36 hours and hadn't taking anything else. He was already taking Ibuprofen for the tooth issue, but was also using it to relieve some of the symptoms and if it was indeed that he may have contracted something after that. He hadn't been to the doctor but for checks ups in years and years.  Time of Onset (24-hour clock): Caller stated it started about 1-2 pm in the afternoon on Friday 02Apr2021 and came on very quickly. The events did not require a visit to emergency room or physician office. The outcome of slight pain at left shoulder where the injection site was at was recovered on 01Apr2021. The outcome of diarrhea, fatigue, sinus drainage was not recovered.  No follow-up attempts are needed. No further information is expected.
