The patient also took Tylenol 3 (300-30 mg) a few hours after getting the vaccine to help with the back pain which was aching really bad. Her back pain woke her up on 21Mar2021. Her back pain was much better on 22Mar2021. She always some back pain but the back pain she had after her second COVID-19 vaccine shot was really something, it was really bad, more immense than she was used to. She also felt real tired after she got her second COVID-19 Vaccine. She didn't want to do anything. She was not nauseated. When she checked her temperature, it was 99 degrees. When she checked her temperature again, her temperature went to 98 degrees and then to 97 degrees. She doesn't take pain medication for her back unless she absolutely has too. She had bought Voltaren (clarified as generic diclofenac) when she was there. She did not like to take it because she believed that the diclofenac maybe bad for her liver or kidneys. The patient also had leg cramps during the night after she got her second COVID 19 Vaccine. She has had leg cramps since the 1970s and to scratch the leg cramps from her list of COVID-19 side effects. When she gets leg cramps, she takes potassium. She had 3-4 bananas and a squirt of liquid potassium in her mouth after she had the leg cramps. Sometimes, she would take a Valium but was told not to take it with the Tylenol #3. She ended up in the hospital once with leg cramps. The hospital gave her a shot of Tylenol. She thought she had a clot in leg. The Tylenol shot was through an IV, and the Tylenol shot relaxed her. She didn't know how much Tylenol she was given, but the Tylenol helped her. She thought she did not drink enough water. Her leg cramps were so bad, it felt like her legs were tearing apart. She would take Potassium, Valium, "Highlands", bananas, and tonic water to treat her leg cramps. She has tried everything. She said that the tonic water had quinine in it. She said she thinks she just needed to drink more water. She restarted taking 1 fish oil supplement a day approximately 2 weeks before she got her second COVID-19 Vaccine.
