Dick Van Dyke has cracked the case!
The Hollywood vet tweeted Thursday that his headaches have been caused by his titanium dental implants. "Has anyone else experienced this? Thanks for all your replies," he wrote.
Van Dyke, 87, first revealed he was under the weather — and without a diagnosis — in April. At the time, he was forced to cancel a New York event, citing "fatigue and lack of sleep resulting from symptoms of a yet-to-be diagnosed neurological disorder." He tweeted about his pain and shared his long struggle to find out what was behind it.
"My head bangs every time I lay down. I've had every test come back that I'm perfectly healthy. Anybody got any ideas," he asked. "It has been going on for 7 years. I've had every test you can think of, including an MRI and spinal tap."
Van Dyke is known for both his iconic film and TV roles. On the big screen, he starred in Mary Poppins, Chitty Chitty Bang Bang and Bye Bye Birdie (the Broadway production of which he also starred in). He is also best remembered for the long-running TV series The Dick Van Dyke Show and Diagnosis: Murder.
He received the Screen Actors Guild's Life Achievement Award this past January.
