My ears have a constant pressure in them. not enough to be very painful, but it can be uncomfortable. it comes are goes. i can also hear a crackling noise in my ears just by moving my mouth. will this go away on its own? its been this for few weeks?

Eustachian tube: Your symptoms are suggestive of eustachian tube dysfunction and it would be prudent to see a doctor, preferably an ENT doctor. There may be fluid accumulation in your middle ear. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
