Hey hun, this really worried me too.. i caught a pretty bad flu 3 weeks before my op and was left with a cough til the day of my op. As long as it’s not a chest infection you’ll be fine. I’m 5 days postop and coughing has been really painful and I lost my voice for the first 3 days. Keep hydrated, take vitamins and don’t overwork yourself these next few days. You’ll be fine 🙂 x
