stiffness

MND is progressive and causes muscle weakness, stiffness, and paralysis that gets worse over time.

It enhances joint mobility and reduces joint stiffness.

An arthritic joint may be uncomfortable to strength train, but inactivity leads to stiffness, which can make pain worse.

About 1 in 150 people will experience more severe symptoms such as high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis, according to the World Health Organization.

In March, the BBC reported how Mr Durose had been prescribed diazepam for a chronic condition called hypermobility, which can cause fatigue, pain and stiffness in joints and muscles, and for joints to dislocate easily.
