Please help MII (my)

*** UPDATE*** MII made it through his MRI which they were not sure he would and so far no call so he has made it through the night! They found he had a severe brain infection which they think is due to his Is cerebral hypoclasia, and they are pumping his with meds now to treat the infection❤ John and I have discussed this situation and if MII is strong enough to keep fighting we are not going to give up on him!! Anything will help even a dollar every $1 adds up and is appreciated more than you could ever imagine . Hi I am Tammi and my son is john we are looking for help with our little guy. I woke up yesterday and he was lethargic and running a temp, I brought him to the vet they gave him an antibiotic shot sent me home with meds he had a slight temp at 102 ran all sorts of blood work which all came back clear and last night he took a turn for the worse. We rushed him to Tuffts last night When we got there his temp was 105.7 and he was unresponsive, they have done all sorts of blood tests also ultrasounds, MRI's and now are going to do a cat scan they think he may have and infection in his brain. They bill just keeps going up but I do not want to give up on this little guy he is only 4 months old if anyone could help it would be greatly appreciated especially this time of year I know how hard it is for everyone. ❤
