Hello!
The erupting wisdom teeth have caused something known as Pericoronitis, that is the inflammation of the gums around the tooth leading to swelling, pain & bleeding. Since you are 22 years old, there are chances the wisdom teeth might erupt completely. The eruption forces are there till about 25 years of age.
Next Steps
You need to visit a dentist & get x-rays done (Iopa - one each for each wisdom tooth) or an Opg from any diagnostic centre. If the x-rays show the teeth to be positioned correctly with chances of eruption, then just give it time & take prescribed medication, but if the teeth are not positioned correctly, then extraction is the only solution to relieve you of all the trouble you are going through.
Health Tips
Start using a mouthwash & avoid hot & spicy food as it will aggravate the swelling.
An anti-inflammatory will give you relief from the pain & swelling.
