What is this kind of pills methyiprevnisolone i think it some pain but i want to know if its safe

A steroid for pain &: Inflammation. Similar to prednisone, which i prefer (less sodium retention), which is quite effective for pain relief caused by inflammation. It is safe when used properly, but you should have been given a likely diagnosis by your practitioner, and there should be a plan to quickly wean the dose, so you don't have side-effects, which are uncommon in short term use!
