My question is: is diving causing my headaches?
History: In November, ~4 days after a dive, I had severe shooting headaches on my right side. Was treated for sinusitis for over a month with various drugs and little success. A CT scan eventually showed no signs of sinus infection, so that has been ruled out. No rash (shingles), and the pain was always better in the mornings, so no MRI ordered. The headache slowly went away on its own after many weeks, a little better each day.
After the headache was gone, I did a shallow 15' max, 1 hour dive last month. No problems, and no headaches. Last week I did at 60' dive for 30 minutes. Now, a few days later, the headaches are coming back, same symptoms, but not as severe as the first time.
Is there any evidence that diving can cause headaches like this days later?
