Thank you for the quick reply.
The symptoms you have described of having numbness and buzzing on your right leg along with sometimes hands and tongue can have all kinds of different causes, as it is a symptom of many different diseases.
It usually arises from damage or disease of nerves.Its most common causes are:nerve compression syndromes, pressure on the spinal nerves such as that due to a herniated disk,diabetes, stroke,transient ischemic attack.Also this can be due to :Underactive thyroid,abnormal levels of calcium, potassium, or sodium in your body,lack of vitamin B12,certain medications.
Nerve root compression(pinched nerve) seems to be the most probable cause of your symptoms.
The underlying cause of numbness/buzzing and tingling should be identified and then treated by your doctor.
You need following tests:
-Nerve conduction studies,
-Certain blood tests,
-Electro physiological studies
-Nerve conduction velocity (NCV)
So I advice you to make an appointment with a neurologist for these tests to know the exact cause & hence its treatment will be done accordingly.
Hope this helped.
