Strep throat or sore throat or post nasal drip

Okay so my throat hurts, i’ve taken pictures and i don’t think there is any of that white stuff in the back. It doesn’t feel like anything is dripping in my throat, but i do that thing where i breath in and breath it to collect the snot that hack it so it’s in my throat if that makes any since then i normally just swallow it. I don’t have a cough mainly just a throat in pain, is it strep ? or just sore with a cold ? or post nasal drip ?

Also my throat feels itchy at the top
