Eye pressure with inflammation.

Hi, I underwent barrage laser for retina holes and lattice in Feb end. I then got a mild allergic conjunctivitis around 5 days after which was treated with steroid FML drops in the next 10 days. Everything was going back to normal when yesterday my one eye turned red. So i went to checkup. My doctor said my eye pressure in the inflamed eye is 20 and other is 15. So she is suspecting glaucoma. But for now she gave me same drops and antibiotics again for 10 days and will have recheck for glaucoma. I'm only 29yrs and no history or vision issue. I got really scared what caused increased pressure and if i really got glaucoma. Can you please tell me if inflammation caused high pressure or its really a risk thing i need to consider? Thank you!
