Yes Katy, they come and go, most annoying. My cough has improved and ramped back up several times and I am 3+ weeks. This past week I coughed so much i pulled a muscle on my side, felt like a knife stab everytime I coughed. Yesterday my husband's legs started aching again... he said it perfectly, this virus doesn't want to let go.
You are approaching the safe zone though and each day you are getting closer. 🙃
