Feeling itchiness in the throat after belting high
Hello everyone, so I was belting at the church in the morning and I was holding the high note I felt itchiness in the throat. I stopped singing and as I was talking my voice started becoming hoarse. I went on a 3-hour vocal rest and as I was eating, I felt a lump like sensation and started coughing. I am scared! I hope and pray to God it's not a polyp, nodule or cyst.
After the 3-hour rest I was sounding normal but the itchiness, scratchiness still exists. Please help. I don't know what's going on. I was just trying to grow my chest voice ( although I didn't warm my chest voice correctly).
