The nurse was going to give her Benadryl but did not as her signs and symptoms were resolving. She was asking for recommendations/clarifications on whether she should get the second dose given her reactions. She never had that type of reaction before. She had had sensitivity to pollen and narcotics. She read that she should not receive the second dose given her reactions but was asking for clarification. She would like to get the second dose and bought an Epi pen. Throat tightness and high heart rate didn't last for more than two minutes maximum. She visited websites and was directed not to get the second dose. She wanted to be 100% certain in regards to whether or not she should receive the second dose. Stated tightness in throat wasn't really that bad. She felt throat tightness previously when smelling perfume. Stated it wasn't anything to be frightened about. She also stated some websites said it does not matter and some websites said not to get the second dose. Also wanted to know if having the Epi Pen would help. She added that she explained reaction to the physician who advised her to get an Epi Pen for the second COVID Vaccine dose. She only had allergic reactions to pollen and perfume.
