Can I Run Even Though my Lipoma Feels Like It's Hitting a Nerve?

I recently found out I have a lipoma on my lower right back. Apparently it's hitting a nerve so there's pain going up my back and down my leg. The urgent care doctor prescribed methylprednisolone. It's been almost two weeks since I was diagnosed with my lipoma. My lower back still hurts and my right leg feels different. I'm impatient so I was wondering if it's alright to start running again. Also should I be worried that it still hurts to sit down?
