My Stimson Python (aged 3 1/2 yrs) has been looking and acting kind of weird. I noticed last night that the way he was laying made his head look weird, like i honestly thought he was dead cause his head was on such an angle. He's been laying in the same spot for the past couple days. I checked on him at about 11:30am today and he looked the same so I reached in a poked him with my hook and he just looked up and i swear i can see a lump under his right side of his jaw/neck. then he started shaking his head side to side it was so random i've never seen him do that. https://m.imgur.com/UX2uSWV I had to leave after to go to work so my mum is just at home with him. He last fed on 29/05/17. but i don't know when his last she'd was ... Doesn't anyone know if he's sick or is his just symptoms of a shed? And by the way I've owned him since Nov 2013, so it's not like I haven't experienced his sheds before. but i'm so worried!!
