Narrative:

At top of climb I smelled a strange odor. I mentioned it to the first officer. He smelled it as well. I called the flight attendant and asked to take a restroom break. While in the back of the airplane I walked to the back galley to see if I could tell a difference in intensity throughout the cabin. I could barely smell anything throughout the cabin. When I went back into the cockpit I immediately could smell the much stronger fumes again. I discussed the situation with the first officer and we decided that we were no longer comfortable with this unknown fume in the cockpit. I took the radios and the controls and instructed him to initiate the emergency checklists. We diverted [to a suitable airport]. Once on the ground we both noticed strange sensations for hours to come. I noticed a numbness in my face; dull headache; and a 'buzzed' feeling. I called the nurse-line that the company recommended and explained my condition. We then went to the hotel and I didn't feel normal again until I woke up the next morning. Find the cause of these fume events and take corrective action.

Narrative: At top of climb I smelled a strange odor. I mentioned it to the FO. He smelled it as well. I called the FA and asked to take a restroom break. While in the back of the airplane I walked to the back galley to see if I could tell a difference in intensity throughout the cabin. I could barely smell anything throughout the cabin. When I went back into the cockpit I immediately could smell the much stronger fumes again.
