Osteoarthritis
"I was prescribed Voltaren gel for my MCP joint, which experienced remodeling of bone after my 14-year career as a deep tissue massage therapist.  I am a chiropractic student, so I went the conservative route first: adjustment, ultrasound, cold laser, Alpha-stim, microcurrent probes.  Finally I had a series of x-rays on campus and unfortunately, there is a large osteophyte on the volar (palm) side of the base of the 1st metacarpal, along with serious lipping of the scaphoid bone which supports it (you know this combination as the saddle joint).  Voltaren helps the crippling pain of trying to unscrew a jar, open a doorknob, or hold a pen.  I will however have surgery to remove the osteophyte."
