Fibromyalgia is a general pain of the musculoskeletal system that lasts for at least 3 months. It may be accompanied by a feeling of tiredness, insomnia and stiffness in the lower body and the limbs.
Parkinson’s disease affects about one million Americans and about 4-6 million people worldwide. It is a neurodegenerative disease of unknown cause, affecting mainly elderly people over 65, but early-onset Parkinson’s disease is not uncommon and may occur among a much younger population, even before the age of 40. Parkinson’s disease is noticeably more common in men than in women.
