Cheek and gum hurts after stitches.

I have extracted my upper wisdom tooth in July. It was healing normally. I see some hard bump on the gum in August.i went back to OMFS and he said to wait till it absorb on it's own or to come back after 2 weeks.I was dealing with lower jaw and neck pain. So I didn't check this out.I went back day before yesterday and he did shave it down. He put anesthesia 3 shots and scraped it so hard and did stiches. I didn't have stiches for the extraction done in July. This is the first time I had stitches. Since yesterday, I feel very sore pain in the top of the gum area and inside the cheek where it meets the extraction site. I feel some scratches on both the area when I run over my tongue over it. The inside of cheek where it meets the extraction site is sore and not smooth when run over the tongue. I feel like scratches. Also the top of the gum area. Is this normal after that procedure? I didn't have this soreness and pain after extraction. I have the pain now. more on the inside cheek area.
