Hello, Thanks for your query. The fact that your pain is occuring with movements indicates a muscle strain. Any strained muscle when stretched gives severe pain. I advice you to follow the below mentioned guidelines - * Give adequate rest to the involved muscle group and avoid any movement that causes pain * Moist heat application to relax the muscles * Local application of muscle relaxant gel * Analgesic medications as needed I do hope that you have found something helpful and I will be glad to answer any further query. Take care
