Hello, Thanks for your query. It seems that you are having pain in your calves specially after walking. It can happen due to- 1. Calf muscle strain and tear - Usually due to overwork and overstretching of the muscles. Recent increase in leg exercises may cause these. Gradual increase in exercise and pain killers with mild anti inflammatory drugs can help +in reducing the symptoms. 2. Muscle ischaemia- associated with diabetes usually. There is acute pain associated with it. 3. Deep vein thrombosis- comes last among the list of probable diagnosis. You may get the initial physical examination, relevant tests and treatment done under care of Orthopaedician . I do hope that you have found something helpful and I will be glad to answer any further query. Take care
