Hi,
During my last few migraines that have been very severe I have had vibrations around my abdomen. They come on over about 10 seconds and then fade away again. The feeling can be very strong and sometimes my heartrate goes up with them.
They are spaced around 2 - 3 minutes and slowly get weaker .. but I have also have weak ones during the next night. They happen during the knife in head phase, which for me is normally about 1am when I am in bed.
Has anyone else had this ?
