Clinical course: The patient was still experiencing side effects but on top of the side effects which were numbness of limbs/arms, lightheadedness, dizziness and heart palpitations. On top of that, had the heavy three menstrual cycle in a month, every single month for the last year and now not even having weekend between them and on her 4th menstrual cycle for the month and this all this Feb. The patient just got off her period 5 days ago and now have it again and she don't take medicine and don't take get vaccines the only vaccine she have had within the last 10 years of Pfizer.  The patient went to an gynecologists like about two months after consistent bleeding and they are the ones that told me like that this was not normal.  The patient ended up getting on birth control (Name could not be clarified hence, captured as unspecified medication) thinking it will stop the bleeding and they gave me signs of 'closure' before they gave me birth control things and she  was bleeding three times a month before I even get birth control. On top of the bleeding there was another side effect, she was just hospitalized (Further hospitalization details were not available over the call hence, Seriousness criteria not checked) for heart spasm (Later clarified as brain spasm).
