In standard US Medicine, this would be considered a term descriptive of symptoms, and not a diagnosis per se, even though in India at least, it has a specific eponym (Grierson-Gopalan) attached to it.
It falls into the general category of neuropathy (abnormal functions of nerves) and more specifically, probably a peripheral neuropathy (dysfunction of the nerves that go from the spinal cord to the rest of the body).
Here in the United States, evaluation would be undertaken to find out if there is a specific underlying reason for the dysfunction, since many diseases are known to damage the nerves. There might also be studies to evaluate how well the nerves themselves are functioning.
A neurologist would be the specialty of choice here to evaluate this condition, and that is the physician who would make recommendations about how to approach therapy. Without an expert workup, no one can make a specific recommendation or prognosis for you.
