Some of the chemical compounds in garlic help to counteract infections of the lymphatic system. Get 2-3 cloves of garlic and crush them. Spread this mixture on top of a piece of bread and eat it. Repeat this process daily and watch for the swelling to improve. Get a full glass of tap water and mix in 1 tablespoon (14.8 ml) of apple cider vinegar. Drink this mixture 2 times a day until you feel better. The acetic acid in the vinegar will help to rid your body of harmful bacteria that can abscess inside swollen nodes. If you are vitamin C deficient, then your body will not be able to fight off infection effectively. You can get additional vitamin C by taking a supplement or by eating the right foods, such as oranges and strawberries. If you decide to take a supplement, make sure to clear it with your doctor. Mix together 2-3 drops tea tree essential oil with 2-3 drops coconut oil. Use a cotton swab to apply this mixture on to the irritated nodes. Repeat this process a maximum of twice daily to avoid irritating your skin.

TL;DR in Vietnamese:
Ăn tỏi sống. Uống hỗn hợp giấm táo và nước. Nạp đủ vitamin C. Xoa dầu tràm trà lên vùng da sưng.
