I Have Had Back Lumber Surgery. Two Rods Or Cages

i have had back lumber surgery. Two rods or cages where put in my lower back. This took place on 9-7 16. The pain I was having prior to was unbearable. Since surgery I have some discomfort but nothing like before. My left button and upper thigh have some tingle and no surface feeling. I believe I would feel if it was deeper. I went back to work as an CNA last week since then my groan eara is painful on my left side and well as I walk funny now. I was wondering if this is connected somehow? Thanks for your time.
