Laryngitis / Sore Throat / Vocal Cords Inflammation removes stutter 80% !!

Has someone else experienced a similar case, always when i catch a cold and have a sore throat my vocal cords get inflammed and my stutter literally goes 80% away, what is this causing it to relax or change completly the way i speak. I dont have a severe stutter but it gets worse sometimes time by time, today while working in daily i presented something, i literally spoke 10 minutes straight and maybe stuttered a bit but not as much as when i didnt have a sore throat, my vocal cords are inflammed now completly and i have a raspy voice, but the stuttering has gone away with it like 70-80%.

Whats the science behind this?
