I'm dealing with some annoying allergies that started yesterday, and now whenever I'm in cold air, I can't stop sneezing. I took Allegra last night, and thankfully, the sneezing has lessened today. However, when I cough, I feel a pain in my rib cage. Is this something I should be worried about? For some context, I had a moderate case of COVID about six months ago and my lungs were affected back then.
