Wrong joint

One of the things I do on my job is sell 5 gallon buckets of paint which can weigh anywhere from 40 lbs to 75 lbs.  As a result, sometimes I strain the muscles of my back, never anything serious, maybe a day or two off from work.  Two weeks ago Tuesday I went to see my primary physician for such a problem.  She's new.  Dr. Tock, who I'd seen for years retired last June.  Anyway, she gave me prescriptions for Neproxen and 5 mg of Diazepam, which I found out later was generic Valium.  She said the Diazepam might make me drowsy.  It didn't.  It did, however, make me fall down a lot.  I fell out the back door, I fell out the front door, I ripped a bunch of skin off of my knee sliding down the staircase; I fell down 6 times in one day.  Oops.  Oh, and not only did I still have the back pain, I lost the strength in my right leg, double oops.  When I went back to see her she said the problem was with my knees and I needed to see an Orthopedic Specialist.  So, I made an appointment for the next day and they took 8 x-rays of my knees.

Well, my specialist looked at my x-rays before he came into see me.  When I explained what was happening he said, "it's not your knees, it's you lower back," and sent me down for more x-rays.  Two days later I went for an MRI on my... you guessed it, lower back.  He also put me on a 6 day regime of Prednisone.  Tomorrow I'm going for a test where they're going to stick me with little needles to test my nerve synapse.  I also went on Leave of Absence from my job - it was either that or burn up all my vacation time.  One can only wonder if she got the wrong joint, what else could she have gotten wrong.
