Thank you for posting your query.
Your dad needs to be examined in detail to find out the cause for his intermittent stiffness
of hands and hips.
However, some common causes include calcium or sodium deficiency
problems, mechanical compression of the nerves.
He would need an evaluation by a neurologist
, and investigations such as blood tests for calcium, sodium, thyroid and nerve conduction studies.
Winter does aggravate these symptoms.
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
