So I'm scheduled for surgery this coming Tuesday, Valentine's Day - eeeek! and I have managed to come down with a cough. Not a cold but a crazy cough. No cold symptoms although I do feel slightly fatigued. No fever. No runny nose. No congestion. But a wicked cough that kicks in every couple of hours and is absolutely show-stopping. I'm worried that I might need to reschedule. My doctor says to let him know how I feel over the weekend and that rescheduling is no problem but I'm just so anxious to get this done and I've been waiting patiently for what feels like forever but I'm sure it's a terrible idea to undergo a major surgery with a compromised immune system. Thoughts? Advice? All appreciated. Thanks!
