Right side ear, nose completely blocked.

I have some pain in the right side of the mouth upper and lower jaw. I initially thought it might be a tooth pain.the pain is on upper and lower end of the tooth in that side. I see some swelling on the lower end of the jaw under the ears. My nose and ears completely blocked. I feel pain inside the ear. It's like pinch scratching pain. I feel the same pain in the lower end of the jaw too. I feel some discomfort in the entire right ear and the lower jaw end. The swelling is little and its under the ears near the jaw end. I feel Feverish and chills. But temp is normal. What could be the issue? Is it because of tooth or ears or sinuses? I used to get sinus issues often. I am in USA and difficult to go to doctor or dentist to check. When I swallow something or just saliva I hear the sound inside the ears.when I open my mouth, I hear the popping sound in the ear but it's not relieving the blockage. That is still the same. Please help.
