Earlier this week, Jack Osbourne revealed he had been diagnosed with Multiple Sclerosis, but what he didn't say was how he figured out what was going on. Now, he's talking about what led him to seek help. 

Jack Osbourne has revealed that his failing vision was what caused him to go to the doctor.

He says "I couldn't see anything in front of me" so he went to the doctor and found out he had Multiple Sclerosis. At first he said he was angry and couldn't figure out why he got it and why he got it now because he and fiancee Lisa Stelly just had a baby girl back in April.

Multiple Sclerosis is a disease that attacks your autoimmune system and it affects your muscle control, strength, vision and balance, but neurologist Dr. David Snyder of the Multiple Sclerosis Research Center in New York says that Jack can still live a full long life and with drugs and treatment, the debilitating effects of the disease can be kept at bay.

Jack's mother Sharon Osbourne broke down on Monday's episode of her show The Talk when opening up about her son and his diagnosis, but was in better spirits when she went on Conan to talk about it. Sharon says that Jack is "in good spirits" and is "ready to fight the disease" and that the outpouring of support means a lot.
