Hard to know how to care. At dentist office for a routine cleaning we found three abscessed teeth with a lot of infection. She had not complained of any pain and when asked she denies pain. Had a total hip replacement and never took any meds. Experienced a very very bad U.T.I. never with any recognition of pain. I'm beginning to think that the part of the brain that feels pain has been compromised. Is this possible? Has anyone dealt with this problem. She is able to converse for short conversations most of the time. During her adult life she had a high pain tolerance but this is unbelievable. Thoughts?
