I am getting back pain at the age of 26, would you share me your advice on it?

I am 25 and just today I found out I have degenerative disc disease and arthritis in my lower back. I got it from an injury I had a few years ago. If I lift anything too heavy, it sets it off and I hurt for days, sometimes weeks. I take darvocet for the bad days and ibuprofin and icy hot for the not as bad days. I have to start physical therapy, but thats all I can really do. It's something that wont go away unfortunately.
