@hikeema123 I’m sorry that you have all that throat mucous. I looked at your profile and it seems like you have some GI issues. Wonder if th excess mucous could be part of that.
MMP

I included this info on MMP but I don’t think you have it . MMP causes sores in mucous membranes, not just the throat.
What does your doctor say about the excess mucous? Have you seen a dentist to ask their opinion?
