thank you all for the wonderful advice and suggestions you offered!
to update you all on his condition, his tremors have slowly gone away, they're more frequent in the morning and late at night but for the most part he's not doing it as much as he was during the weekend. thanks to the advice of everyone here, i did record this on video (which i can share with you all if you'd like) to take to the vet. i did notice a bit of lethargy on his part though, he doesn't seem as energetic as he usually is nor does he squish his rubber balls as much as he usually does (i think he likes the squishy sound it makes) but am under the impression that it causes discomfort.
i was able to take him to the vet yesterday (Monday) and we got a bunch of tests done... she told me he looks great physically. i just received the results and honestly it's been a little frustrating. the vet said everything looks fine, his T4 is 1.6 (though i have to say i'm a bit annoyed bc when i asked the vet if it we were doing a full panel test she told me yes >_<) which she tells me is normal and that i shouldn't worry about... but from what i read here, isn't that too low for a golden?
and the absolutely unexpected news is that they found some chloride and phosphate crystals in his urine!!! she says it's not an infection right now but she'd like a first pee of the day urine sample and she suggested that we should change his food to one of their prescription foods for preventive measures.
i'm wondering if i should get a second opinion. this was so unexpected on so many levels. she said for now all she can suggest for me as far as the tremors goes is that i should just log them down on a calendar and check for unusual factors that might've occurred that day.
honestly i feel a bit frustrated by all this
