You may have a virus or an infection brewing. Try not to overanalyze. The lymph node is probably a reaction to fighting whatever is brewing. If you have it in a month, that does need to get checked out. Unless it starts to hurt, I'd just do the usual things of gargling with salt water, sleeping with a humidifier if you use heat in your home, drink tea, etc. Get some extra rest. And maybe your body will fight off whatever is trying to happen there. I get sore throats from time to time that start to where it is scratchy or feels swollen. And it might linger a day and then it goes away. I feel like I probably fought something off. And other times, it keeps on going and I get a worse sore throat and the rest of the symptoms. So, wait to see what happens here. But sore throat is often a virus and going to the doctor is unnecessary for viruses. Only if it really hurts or you get a fever do you need to see the doctor. Oh, and ibuprofen works wonders to take pain down a notch should you start to develop more classic symptoms. But really, you don't need to look at your tonsils. Just go by how it feels. good luck
