Pain in gum long after tooth extraction

[Eric465]

I have had my back upper teeth extracted about 1 year ago, and wear a partial denture. Recently I have been experiencing sharp pain in one area of the gums where a tooth was extracted.  When it started, I was able to relieve the problem by taking ibuprofen. This is no longer working, and neither is the stronger pain medication I tried.
The pain used to be triggered by wearing the denture. Now it comes on when I am physically active even when I do not wear the denture.

The only way to get relief is to put cold water or ice in contact with the gum area.

The pain is also triggered by vinegar or sugar. coming in contact with the area.

Examination by a doctor found no sign of infection or swelling.Neither the doctor or  my dentist has been able to recommend a treatment.

Did they take an x-ray to see if there may be a root tip or other possible broken piece of tooth in the gum area?  

Was the denture adjusted at all to make sure the fit is still proper?  It may be rubbing a sore spot and causing an irritation in the area

In  April, I visited a maxillo facial surgeon who saw a sharp bone protrusion that may have been the problem. The removal did not fix the problem. The denture was adjusted and checked for proper fit.
As I said, I was able to live with it and took ibuprofen to stop the pain until a few weeks ago, when I had severe pain and a few sleepless nights. I have had to stop wearing the denture. Even so I get bouts of pain from physical activity such as lifting, even playing the violin, or even eating without the dentures in place. The pain is less severe than that associated with wearing the dentures and goes away after a couple of hours of treatment with ice and ibuprofen. It is not entirely predictable and a I have put in a day of heavy hiking without a problem.

I am going to make n appointment with the maxillo facial specialist again to see if he can figure out what is wrong and find a fix.
