Migraine-gene-discovery-could-lead-to-new-pain-killers - looks like they may be able to potentially find medications to increase our pain threshold. Gotta love that!
It is believed that it controls the sensitivity of pain nerves in the brain and if faulty can bring the threshold so low that just living is painful.
This is why migraine sufferers are so sensitive to light, sounds and even touch.
But the gene is also susceptible to being switched on and off with drugs which means that it could be altered to increase the threshold to such an extent it eliminates the feeling of pain altogether.
