I Had Tingling In My Left Arm For 6 Months

I had tingling in my left arm for 6 months went to Dr then spine specialist. I then had tingling actually more weakness in my left leg... a few months later I had a discectomy C5-6 and fusion and corpectomy. Now a year and half later still have the leg weakness and now tingling in my upper left side of my back. Could it be MS
