[luckyrm]

Hi guys, i actually here is the full story.

BACK STORY
My hamster fell sick a few days ago
at first it had random seizure sort of thing and then stopped eating/drinking/peeing/pooping etc. It also shivered a lot and occasionally groaned.Two days ago it started to bleed from its mouth and nose. There is a hard bulge on its left side but I am not sure if its food or smth else. It is not moving at all and barely breathing. Not opening eyes.It has something white that came out of its private part that is like a cooked rice sticky?.
Barely moving and drinking even if fed with a syringe.Paws are reversed and excessive shivering.

CURRENTLY:
TODAY,IT SUDDENLY RECOVERED AND BECAME BETTER. MY HAMMY SUDDENLY LOST FUR AROUND THE LUMP (HARD- LOOKS LIKE A BRAIN) IN THE MORNING. ITS EATING FLUIDS AND WATER WELL. OPENED EYES. LEFT LEG DOESNT SEEM TO WORK BUT REST OF ITS FEET WORK. ITS LIMPING. STILL NOT EATING SOLIDS. ABLE TO PEE AND POO. BUT THERE IS A BULGE AND STILL QUITE WEAK COMPARED TO BEFORE. IS THERE SOMETHING I CAN DO TO HELP IT RECOVER OR FEEL BETTER. AS OF NOW, I CANNOT BRING IT TO THE VET UNTIL NEXT FRIDAY SO IS THERE SOMETHING I CAN DO BY THEN?

I HAVE ATTATCHED BEFORE, LUMP.
