I have had chronic sinus problems my whole life and I almost always have a swollen gland or two when I have a sinus infection. Everything up there is super connected and a sinus infection can affect eyes, vision, facial pain, skin sensitivity, throat, swallowing, ears, hearing,e verything! Swollen lymph nodes typically happen with any infection, but doesn't necessarily mean its something serious. You likely have swollen lymph nodes frequently and never even know! If you are worried you should always check with your doctor though.
