I seem to have a somewhat recurring problem where during a dive, I will get a stiff neck. Turning side to side is painful while tilting my head up and down is not. When diving locally, I associated it with a combination of cold water and perhaps a stiffer hood/neck piece (its integrated into my wetsuit). However, during my recent trip to Yap and Palau, I also encountered it (no hood, warm water). While movement is VERY painful when it stiffens up, generally, the pain subsides significantly towards the end of the dive (shallower depths for a period of time?) and by the time I am on the boat, there may be some 'tenderness' if I rub my neck, but I have full and complete movement and even the tenderness is gone within an hour after the dive.
While I haven't been able to isolate the symptions, its seems to be (1) more only at depths greater than 70 fsw (2) when my head is relatively still for longer periods of time and/or (3) when I have been at a horizontal and or slightly heads down position.
On this last trip if happeneded 4 or so times out of 38 dives....to the best of my recollection all at the front of end of the trip....where coincidently, I was NOT diving Nitrox. I had initially thought it my be related to a slightly different length / position of my primary air hose due to (1) using a DIN adaptor this time and (2) perhaps during setup, the tank not being precisely positioned in the BC. The other thought was the increased 'pressure' from depth and at one point, I thought it might even be a symptom of 'narcosis'..which seemed to be consistent with it not happening during the time I was diving with Nitrox BUT also could be that my neck was getting stronger in response to the increased resistance to neck turning I was experience due to hose length, etc...I am guessing.
From a physical sitution, I work out consistently -- although I don't tend to work on my traps or neck, but do shoulders.
Anyone have any thoughts or similar symptoms?
