It may sound like you have a condition known as sinusitis. Sinuses get inflamed when spaces around the nose are filled with too much mucus due to colds, flu, allergies, or other conditions. This can lead to pain in your head especially when you lean forward or cough/sneeze; it also causes swelling in the eyes, nausea, and vomiting. To feel better try using warm packs on your face and take pain relievers that can be bought over the counter. Keep yourself well hydrated and rest enough too. In case these signs don't go away, you should see a doctor who will check them out further and treat them accordingly.
