Im sorry that happen to your poor Maddie but let me tell you what happen to someone i know...I have a co-worker who went to vacations to Puerto Rica..
Her and her hubby tour around, came back about two weeks later...So she came back to work, after a couple of weeks she started to complain about how much her head started to hurt only on her right side...Then she started having headaches everyday on the same side...I told her she should go to the doctor and tell him about it...They ran lost and lost of test and couldnt find out what was rong with her...So then she felt like the docter wasnt doin much for her so she looked for another doctor...This new Doc. asked her alot of ?? till it came down to were he said he was gonna have to cut her hair right on the spot she complained about so they did and guess what they found
?????...YES a magget...A really big, fat magget...She also got it from a fly...So what they had to do was the worst...She had to keep that magget in her head for 3 more days knowing it was still alive...The reason why they did that was because like i said it was still alive in a bit far in the head...They put something like a tape to cut the magget from getting any air and making it come up for air...Anyway it ended up dying and the doctor pulled it out and that was that...So dont feel bad it happens to humans to not just pets....
