Sockeye, I have to agree with TSandM. I had small headaches after dives, even with I used nitrox 32, 34 or 36. So, after reading some of the posts about headaches, the next dive out I focused on breathing deep, and exhaling deep. Not shallow breathing either way. Guess what? No headache. Not since, either. You must tell yourself when you are down to breath slowly and deeply. TSandM says it all and so does Dr. Deco, and from more experienced divers than myself. As for the shoulders, no comment from me there. I get migraines, so I understand headaches, but my headaches after diving were not a migraine. And now, I am doing well. I stopped drinking all sodas and never drink caffienated beverages. I drink gatorade or other beverages for athletes. I begin hydrating the day before a dive (I wear a drysuit) and taper off just before my dive. Then begin the heavy hydration process after I am out of the water. Practice deep and slow breathing. Watch your consumption rate as mentioned. Keep us posted okay!!??
