His wife noticed he had swelling in his thighs. He made a appointment with his primary care physician and was told he had swollen lymph nodes in the tops of his thigh. All of his weight loss pulled the skin back and his wife noticed the swollen lymph nodes. During this period of time, he had a CT scan of his chest and abdomen and it showed other swollen lymph nodes. About the 2nd week of Oct2021 he got a call that wanted him to get the booster.
