Having never been "OMM'ed" before, I my first (and only) experience (other than what my fellow students and I do to tweak each other in lab every week) involved a sore wrist. I've had problems with the wrist at various times since 1988, have had it x-rayed, braced, and injected. Nothing but time has helped (the tenderness would go away after a few weeks each time, with no real "triggering" events that i could link to the wrist).
During the 3rd week of school my wrist was so bad, i could barely take notes. I could extend the wrist MAYBE 15 degrees, and flexion was at maybe 30 degrees. After lab one day, I asked my advisor (who's something of a Guru) to take a look at it. He asked me to get on the table, and proceeded to work me over, from the feet up. When he got to my right shoulder, he said "Ah HA!" and "Sorry, but this is going to hurt a bit." He then pushed, pulled, tweaked, and rearranged my shoulder to his liking (no HVLA, just remodeling).
He asked me what I had done to my right shoulder and the answer made the problem seem a bit obvious... lots and lots of shooting shotguns, playing polo, shot/disc in HS and other shoulder-injuring types of moves. Corresponding with the onset of wrist pain, incidentally.
He then handled my wrist for a few seconds, said "Hummm, kinda crunchy, but it's not the problem, your shoulder was." He advised me to leave it alone for the weekend, take advil if my shoulder hurt from being rearranged, drink lots of water and let him know if it didn't improve. By monday my wrist was COMPLETELY pain-free, with extension at about 80 degrees and flexion at 60 degrees (equal to my left wrist). A month later, and everything is still good to go.
I already believed in OMM... i've seen amazing things. But I also know what I was dealing with and for how long my stupid wrist has hindered me (for example: I did all my push-ups in police academy on my knuckles, to avoid pushing my wrists into extension).
Now i just can't wait to learn some "really good stuff" so i can go back and OMM my friends and family. I tell my friends that I want to be an OMMinatrix... or maybe just a black belt in OMM. 😀 😀 😀
