If you are experiencing symptoms already, remedy them before it gets serious! I have had on & off back pains due to several accidents & strains. If you "tough it out," you may be inviting relapses. Are you using a soft weight belt? are you distrubuting it evenly around your waist? Must you use such a heavy tank?
If you need a chiropractic adjustment, massage, or acupunture to assist the healing, call these resources & describe your pain to see if they can help you. Don't let soreness become constant pain. (I am an artist, not a Dr.)
