I have tried all of the above...and that is possible...about the alchemist...I will have to watch who says that to me. Thanks!

You can find out if you have a disease or not, go to the spells menu and scroll to the bottom where it says status effects or something like that; if you have a disease there will be a negative effect of some kind in red writing, and it will tell you the name of the disease. I had one called Ataxia, think i got it off a Screever, it lowered the chance of lockpicking/pickpocketing by 25%, a cure disease potion fixed it. If there is nothing in the list then it sounds like a bug.
