Hi,
It could be a problem related to nerves. Please go for EMG of muscles and MRI of brain and spine. There are some diseases that cause stiffness of muscles like Fibromyalgia, Multiple sclerosis and Amyotrophic lateral sclerosis. Please consult a physician and neurologist for complete examination, diagnosis and treatment. Hope this helps you. Take care and regards!
