Uneven breasts 3 months post op. Would revision be the best option for me? (Photo)

I had breast aug done 3 months ago. Initially after surgery, my breasts were pretty symmetrical with my left slightly higher than right, I assumed due to swelling. Now, my right has a natural shape while my left is still higher and more round, i also had pain only in my left during recovery. My surgeon put me on singulair 6 weeks ago and believes its early encapsulation. Would revision be the best option at this time? Thank you. (300cc moderate plus both sides)
