Thanks for posting your query.
From description , it seems radicular pain
in leg due to compression or streching of nerve
I suggest you to consult an orthopaedician nearby for a detailed clinical and neurological examination.
Your doctor after diagnosing the condition , may send you to a physical therapist for muscle stretching and strengthening exercises.
You can take neurobion
forte and calcium tablets after consultation with your doctor.
Wishing you good health
