I had a throat issue last week. Well, my dad came down with something and passed it on to me after a few days. I haven't been sick in like 10 years and didn't know what to do, lol. I had a weird week, sometimes cold, other times tired, feeling like there was a bubble in my throat, etc. The doctor said I had a minor respiratory infection in lungs. I tried to stay home a lot so as not infect anyone else. I'm fine now.
You probably have the same. Eat soup and lots of fruit. Do some walking in the sun and try to stay active. Well wishes.
