A cold ruined my progress
I was making good progress on my costo, I'd say I was 50% better. And then I got a cold last week - now the cold has died down, but my chest pain is back to square one how it was since I first got costo. Has anyone else experienced this is it normal? Why would a cold even affect costo in the first place? I wasn't even coughing or sneezing, it was just a normal cold.
