Anyway, since the runs, he has had several solid bowel movements, all back to normal! The SM symptoms are still crawling back in, but atleast the latter has gone. We rang up Stephanie today to see what to do from here and she said to put him back up to half a steroid a day rather than what we are doing now which is every other day.
He has been pretty bad today aswell in the morning, he was sitting there and just being perfectly normal then all of a sudden his head jolted (really violently) to his back left leg and started really violently biting his back legs repeatedly and you could see him shaking and everything as he did it. This particular episode lasted about 5+ seconds. Then later on in the afternoon he did it again but worse and for slightly longer.
Also more footage of the "fly catching" caught last night after him limping quite badly then face rubbing: (this is just for researchers or anyone that might be interested in this kind of footage for diagnosis)
