Heel pain after COVID-19 vaccine

Five days before my first Covid 19 vaccine, after several hours of shopping and walking, I suddenly developed a bruised feeling under my right heel. Thinking it was from poorly fitting shoes, I next day switched to more padded and supportive shoes with a good arch support and gradually it began to subside. One hour after receiving my first vaccine shot, after sitting in my car all the hour, I stepped onto the parking lot to go shopping and felt the pain in my heel so strong that I couldn't walk! I sat down to stretch and massage my foot and then limped into the store to briefly shop. I lived very far away from any doctors, so wanted to stay close to the vaccine clinic for a while longer to make sure I had no serious side effects. For a few more days I researched causes of heel pain and called my doctor about it. I had guessed it was Plantar Fasciitis because the symptoms and relief from suggested therapies matched my own. My doctor suggested the vaccine caused inflammation and said to take tylenol if I needed it along with stretching, massage, icing and using arch supports. Two weeks after the second vaccine shot, along with intense self therapy, the pain is very gradually subsiding. It is very upsetting because I have never had any type of foot discomfort in my 72 years and some people in medical blogs said their intense discomfort wouldn't go away. Finally, yesterday I discovered wearing Nike Hyperdunk basketball sneakers with Heel the Pain inner soles completely eliminated the discomfort along with continuing the manual therapy. If it returns, I will visit my doctor. Is anyone else suffering from this condition and what is your story?
