What does chronic mild interstitial prominence in the chest x-ray report reveal?

Hello doctor,

I recently went to the emergency room (ER) because of the worst shortness of breathe within seconds while lying down. I have never had this in my life, and it lasted several minutes before it started to go away gradually. I felt like I was suffocating and came close to losing consciousness. When they did x-rays, they told me that I had pneumonia. But the test results were mild central interstitial prominence, which appears chronic in nature, and the doctor did not even bring up to me. When I got back home from the hospital, the severe shortness of breath started occurring again. But rolling on my side before it became full-blown had made it stop. What does mild central interstitial prominence, which appears chronic in nature, even mean, and what could cause it? When I searched for it on the internet, it directs me to interstitial lung disease. Kindly guide me. I am currently on Diclofenac sodium EC 75 mg, Bupropion SR 200 mg, Quetiapine 50 mg, Sertraline 100 mg, levofloxacin 500 mg, Pantoprazole EC 20 mg, Baclofen 10 mg, Cyclobenzaprine 10 mg, Hydroxyzine HCl 25 mg.
