Bless your heart, tigerlily, this type of hurt can mar someone's life, especially if the abuse was in childhood. It may not hurt as much anymore, because you may have built up outward defenses, but the thing is, it still hurts, and it may be affecting you physically.
I would first make sure that the discomfort doesn't have a physical source. If it doesn't, I would suggest counseling and working on resolving this emotional pain. By your words, I would indeed suggest counseling regardless of the physical source. I can almost feel your pain from here. Healing from these types of issues are not always easy, as they cut deep into our soul, but healing is very possible. It just may take some time.
