hi my names jaime im new to this website and hope to gain alot of knowledge and paas from whatever little i know...

I bought a spider morph from some guy on craigslist he looks to be about a year old but i noticed the head do the upside down looking thing so i freaked and thought it was IBD (INCLUSION BODY DISEASE) so i held him by the tail but he was normal which was a plus in my eyes. now im worried bout the head wobble whats a rare case of head wobble spider effect and whats a sever case look like? i love spiders alot but i dont want my lil guy goin on me ive searched and read most of this thread but i havent found a sever case of head wobble vs a mild case and havent really read a better detail on the head wobble case ex: if it becomes terminal, does the snake suffer with pain because of this, i know they "supposedly" all have it but i wanna make sure mine isnt screwed sorry for the long post and thanks for any help
