Is It Normal To Have A Clear, Tissue-like Growth Hanging From My Uvula After A Bad Cough?

Hi can you please help me, I went to the hospital yesterday I have something dangling from uvula, it was longer that usual, looks like clear fluid, when I touch it with my tongue it’s like tissue, the dr said it was collection of salvia gland? Should I get a second opinion? It’s making me very anxious. I can flatten it with my tongue and move it around. It’s annoying sensation in my throat. No fever, I did have a really bad cough a few weeks ago. Flu. Ect.. they said gargle salt water
