Similar to me. I could not get warm yesterday until late in the afternoon and I developed a pain in my throat when swallowing which is still there today. Came with a headache and fatigue/brain fog but not much in the way of sniffles.
I've had a throat itch for a few weeks. I reckon it's mild hayfever from a warm winter. I eat plenty of fruit and veggies which is what usually helps me get over a cold.
