Bulkhead need not mean emergency exit row. This depends on aircraft, cabin, and the airline's cabin configuration choices (e.g., as regards relative cabin sizes and therefore where the divider bulkhead is vis-à-vis the fixed emergency exits). Bulkhead rows often have bassinet fittings, which would not be allowed if they were emergency exit rows.

Check the specifics for the aircraft that fly your intended itinerary. You may find that bulkhead seats do not require exit row qualification. They may be hard to get for other reasons, but your medical situation may help.

(If the bulkhead row on a particular aircraft is also an emergency exit row, you would be correct, but that is not the usual situation.)
