question: I HAVE PERPETUAL LOWER BACK PAIN (AT 73 YRS., A MOTORCYCLE ACCIDENT (30 YRS BACK - HAD SURGERY THEN, BEEN O.K. .. BUT THIS SEEMS - POSSIBLY DUE TO OLD AGE, TOO MUCH TIME AT THE COMPUTER (LEANING), TOO MUCH TIME READING (1 -2 HRS. / NIGHT - BUT WITH A GOOD CHAIR, I BELIEVE) TIME FOR ANOTHER MRI? BACK BRACE? IF SO, RECOMMENDATIONS, P.T. REFERENCES? ADVICE IN GENERAL? YYYY@YYYY
