What Causes Severe Pain,swelling And Redness In Throat?

Hello, I woke up this morning with an extremely painful throat. I could not swallow and it felt like something was stuck in my throat. I looked in the mirror and my uvula was extremely swollen to the point that it essentially rested on my tongue. In order to take a picture of it to send my husband back in the United States, I had to use my little finger to hold my tongue down and even then I still could not see the entire uvula. It was extremely swollen and red and there is a little bit of white on it but not pustule or pus sack white.A few hours have passed by as I ve debated going to urgent care. I decided to take another look and while there is still some swelling and redness, it has gone down significantly. It no longer rests on my tongue. There is still pain, however, certainly not as much (it is hard to tell or gauge my pain due to the fact that I took to 100 mg tramadol that I am prescribed by my doctor for pain). But swallowing is a little easier. And a little bit of white remains on the uvula. My tonsils or glands, I m not sure exactly what those are on either side of the uvula, are clearly swollen as well.I m living in Germany and I m entirely alone without any family or friends and I m not sure what to do. Do you think this is something I can take care of at home simply by gargling salt and water? Or would you recommend I d be seen by a doctor? What antibiotics be beneficial here? Anything you can offer for advice is very much appreciated. Thank you.
