I am scared

I had the Solumedrol 250mg. for 2 days last week. I felt rough over the week end and yesterday my legs were rubbery and my spine and legs hurt really bad. Today I can hardly walk to the bathroom and when I get back to bed my legs and spine feel like they are on fire. I would fall if i did not have the walker.
Something different is happening and I don’t know what to do. I put a call in to my neuro this morning and have not heard back. What to do???
