Not able to open mouth wider after WT.

I had extracted my upper wisdom tooth right side in July. I did that because I had lower jaw pain and neck pain. I went to dentist and he said that wisdom tooth could be a reason. Extracted it and still same symptoms. Dentist suspect a tooth root fracture in tooth#46 and told me to extract that. Went to Endodontist and he said he couldn't see any fracture and did RCT. I did rct in September first week. Crown not done yet. After my wisdom tooth extraction, I see some hard bump on the gum of extraction site. I went back to OMFS in August and he said it will absorb on own. It didn't. Went back to him this Monday and he shaved it down. He put anesthesia and scraped that area so hard and aggressive. I still feel soreness and pain in the extraction gum and inside cheek area. He did stitches too. I have a crown work #46 scheduled for next week. Can I do crown work or should I wait till this wisdom tooth area heal and hole close? I couldn't open my mouth wider after extraction since July.
