Thanks for query,
If calf pain on both the side usually it may be due to some strain on calf muscles or running,jogging after a long time.
If it is so then take rest and take analgesics as and when required.
If pain is on one side then it is possible that it may be due to intermittent claudication
due to vericause vein or deep vein thrombosis
Consult vascular surgeon for diagnosis and treatment.
Ok and bye.
