Sudden problem with turntable


I have a rega p5 with a ortofon black. it used to sound great. yesterday i put on a record and it sounded terrible, really muddy. My knowledge of turntables is very limited. Is it possible that i damaged the stylus? Any suggestions as to how i would determine what happened?

+1 @stringreen but since the OP is using the Ortofon 2M Black (as opposed to any MC) he can change the stylus at a lower cost. This is assuming that it is stylus damage, and suspension is still good. As the OP has described this change as being sudden, and dramatic, my suspicion would definitely be on the stylus
Just re-read the post again. My bad. I thought he said the 2M. If it is the Cadenza, Soundsmith would be an option, but be prepared to wait for it to come back. My last cartridge was there for 2-3 months
unfortunately no. I have been swamped at work. Hoping to try over break to fix myself, re-oil bearing, set-up cartridge etc...if that doesn't work I will take it to audio element in pasadena and see what they have to say. I think it would be a good learning experience to at least try...or dangerous..
