I don't know what tylenol sinus is... I looked it up on google and it looks like it are tablets against allergies. I'm sorry if I just repeat what BeDeviled said.
Have you tried a nose spray? I always use a spray that contains xylometazoline. It helps "shrink" the tissues in your nose and clears the stuffiness. This is also very helpful for clearing up the blocked ears. As you know your ears and nose are connected and clearing the pathway with a nose spay helps the fluids behind your eardrums get out.
A disadvantage of xylometazoline however is that with some colds it can really irritate your nasal glands and your throat. This isn't harmful, but after using the spray it will hurt a lot for a few minutes. Since you already have a really sore throat, maybe your mom can get you some other nosespray instead...
For your throat, I recommed buying some tablets that contain a substance that numbs your throat for a while. I don't know what they are called, but I know they exist.
It can also help to take some aspirin or other painkiller, although you probably do that already.
I hope this will help you a little
