Real bad sore throat swollen tonsils arent sore just throat ive had it since wednesday been on zpack for 3 days so far when is it gonna go away?

If vitamin Z doesn't: do the trick after 3 days it's likely you have a viral pharyngitis which is much more likely than a strep throat. Did you even see a physician or was this called in for you like it is done many thousands of times inappropriately every year? Viral pharyngitis peaks at 4 days and then begins to improve almost invariably unless you smoke in which case the residual symptoms can last for a couple week
