Strong lower back pain - tweaked my back picking up 20 lbs 2 days ago. constant pain hurts most when moving. anything i can do to heal faster?

Try...: Unfortunately the primary healer is time but: other than Naproxen you can also try Ibuprofen 800 mg 3x/day. Ice and/or heat may help, and you can also try aspercreme or capsaicin creme. I do not recommend bedrest at all (unless the pain gives you no choice) - keeping up your normal motion and activities (but of course avoid bending/twisting/lifting) should help with the healing process.
