I am not sure about diet coke...but regular Coke contains Phosphoric Acid....nasty stuff dissolves the bones and you need a HAZMAT license to transport it.
Also most soft drinks contain tons of sugar...to be avoided...look at the label.
If you are doing stretching exercises...you may have stretched the ligaments too much ...without appropriate muscle strength to maintain the joint integrity.
X-rays are good...but a Cat Scan is better....
I hate sugary sodas.
Joke:
So a fellow come crashing through the front door of the veterinary office screaming “Doctor, Doctor! My baby isn’t moving”
Doctor takes a look and responds “Yer lil feller is dead. So sorry”
“Can’t be! Can’t be! I want a second opinion!” he exclaims.
Doctor says “Okay” brings in a Russian Blue. It sniffs at the lil feller, walks up one side and down the other, then looks at the Vet.
Doctor says “Sorry, still dead”.
“Ho Nohhhh! Please, I need another opinion, just to be sure!” he pleads.
So the Doctor brings a nice looking black dog which sniffs at the lil feller and it too proceeds to walk up one side and then other and it too looks at the Vet.
Doctor says “Well, that’s three opinions and again, sorry about yer lil feller”.
“Guess I owe you for the visit at least” the guy says sobbing.
Doctor hands him the bill and looks at then exasperated says “What the hell is this? $600 dollars!!??”
Doctor replies “Well yes. That’s $200 for the visit, $200 for the cat scan and $200 hundred for the lab report”.
finito..
