The fact that your pain is occurring with walking or standing 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
* Ice packing once in every 2 hours over the affected area
* Moist heat application to relax the muscles
* Local application of muscle relaxant
medications as needed
If you don't find any relief with the above measures, a detailed clinical examination along with appropriate investigations are needed to establish a diagnosis.
I do hope that you have found something helpful and I will be glad to answer any further query.
