2 morton neuroma removed with a nerve decompression in same foot

I had surgery 4 weeks ago to remove 2 Morton neuroma as well as a nerve decompression and a bone spur in my left foot. I am still having pain cant wear a shoe yet and if my foot stays down for periods of time it turns red and gets hot. I am very discouraged and wondering if this is normal. The doctor has me on steroids gabapentine and tramadol to control pain. Anyone else experience this?
