Therapeutic measures were taken as a result of arthralgia, pain in extremity, myalgia.  Clinical course details: The case was reported as non-serious. The patient wanted to know if he should get another dose of the COVID-19 vaccine. He took the vaccine for 12 and older on 15Sep2022. It was a bivalent booster. He was about 8 days away from having it for 6 months and was inquiring if his injection was still good. He was hoping he could get it today. He has tried 5 times to get another dose at the pharmacy. The patient heard that for the new bivalent booster, there's more protection against BA.5 and XBB.1.5. He remembers there was something that changed right away after he took it. He had joint pain on his left leg after the injection; the entire 6 months. When the effects of the Pfizer vaccine started going away from him, he started feeling ok; his joints felt ok. Stated that that's one side effect that hit him pretty hard. He had to avoid going to shows for a while and he couldn't spend a lot of time anywhere. He kept doing physical exercise and got stronger. He took pain medications every day and stated that could have been a part of it going away. The patient was going to go for surgery but it was cancelled. He wasn't able to get it. He was injected steroids. The pain went from his thigh to his knee to the muscles on the left side. Then, back to his thigh. With the steroid injection the pain went away. He has to take pain medications every day and he was supposed to get a surgery but had to be delayed. The second day after he took the medicine (the COVID-19 bivalent vaccine), he took the chance of going someplace. He went somewhere and he got COVID-19. He figured it would have been the BA.2. It went fast because he had received the vaccine before. The surgery was steroid injections to zap pain out of his left hip. In that same week, the pain went away and was because of the Pfizer vaccine. One side effect of the vaccine was, it happened a couple weeks ago, the pain went away and he decided not to have the operation. He is a class 1 diabetic and his doctor wanted his blood sugar below 200. The pain went away. The pain started in his knee and that was during like the middle of year and then he was doing exercises for knee and leg and pain went up on the left calf. His left leg was really thin because he wasn't using his leg. When he used his leg, he had tremendous pain in the knee and calf. Then the pain went on his hip and he wasn't able to walk but would have to in little steps and kept exercising the leg. Once the effect of the Pfizer medication got to be around 5 months or so, the pain lessened so much and decided not to have the steroid injections in his leg. He can walk a mile. He slowed down lately but he sped up because he went from 2 hours a day studying to 4 hours a day of studying. He was studying COVID 12 hours a day from the time it hit his city and when it became the delta virus, he was studying 10 hours a day. He has went down to 2 hours a day. He was feeling a little joint pain. He has been taking Pfizer for a long time and took Moderna only once. He got a bad reaction from Moderna. The first 2 times he took Pfizer and then Moderna once and last time was Pfizer on 15Sep2022. He started physical exercises last year.
