Neurological bend?

Once I’d finished all my scheduled decompression stops I spent a few extra minutes on oxygen at six metres, as is my practice before finally surfacing after 114 minutes. I still had no pain or any other symptoms of DCI. After getting out of my heavy tanks and filling my BC to float my gear on the surface, I rested for a few minutes. In retrospect I might have waited a bit longer, although I can never know if it would have made any difference. I proceeded to climb up the ladder that leads out of the water and make my way up the twenty-odd metres of rough stairway and loose gravel to the top of the hole where I started to get out of my wetsuit. So much for no heavy exertion after a deep dive, but by then, although I didn't know it, I was probably already not thinking clearly. Within about twenty five minutes of surfacing, I began to see visual disturbances or ‘auras’ as they are called in a migraine headache. I should point out that I do have a history of migraines and sometimes quite bad ones. The problem is that the symptoms I was experiencing at that point were no different to those I’d had with migraines in the past. These symptoms are very similar to those experienced by divers who have neurological decompression sickness! Incordination, lethargy, fatigue, numbness, pain and headaches to mention a few. If it was indeed DCI it meant that a bubble/s of nitrogen or helium had formed during my ascent and lodged somewhere in my central nervous system or CNS. The bubble, or more likely bubbles could be anywhere from the spine upwards to the brain. If not very promptly treated this could mean temporary or permanent loss of memory, trouble walking and talking, hearing problems and other similar effects.
