Hello, Thanks for your query. From description it seems to be calf strain. There is partial tearing of muscle fibres . You can identify this level of strain by the sharp pain at the back of the leg that hurts when walking on it. I advice you to follow the below mentioned guidelines - * Give adequate rest to the involved muscle group and avoid any movement that causes pain * Ice packing once in every 2 hours over the affected area * Local application of muscle relaxant gel * Take anti-inflammatory drugs like Ibuprofen to reduce pain and local swelling or inflammation. *Wrap the calf with a compression bandage to help keep swelling under control. Full recovery takes approximately 5-8 weeks.Be careful not to wrap the bandage too tight. *Keep the leg elevated when seated, and when you need to be up on the injured leg, insert a heel pad in your shoe to help shorten the calf muscle, which takes a portion of the strain off it. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
