I got flu/covid shots. We went to Hawaii. And 15 days later upon return I got the WORSE flu ever. At first I thought it was just I was ill from jet lag but bam it layed me out! Diarrhea, terrible joint pain, esp in my 3 joint replacements. Finally had enough energy to go ER and told it was flu. Alot for a veteran teacher who has only it a few times in 34 years. 18 days later still not 100%. Dizzy no appetite but drinking a lot!
