Can a person be subjected to long term physical pain as a result of psychological abuse Can psychological abuse in the past lead to long term physical pain in the present?  

Pain will usually become less severe as the injury heals, but what about pain not resulting from physical injury?  How does that happen and how can it be sorted out?
The subject area regarding this question is psychosomatic disorders and problems like what you describe can be difficult to deal with.

First of all it is imperative that all physical and neurological causes of the pain are ruled out, including neuropathic problems, through medical examinations and tests.

Psychosomatic medicine involves diverse specialties including psychiatry, psychology, neurology, internal medicine, surgery, allergy, dermatology and psychoneuroimmunology.

Whenever any physical pain arises without physical injury, it is important to see your doctor to get the source of the pain checked out.  If you jump to the conclusion that it is all psychological without seeing your doctor first, you could cause serious problems now and further along in time.

It is possible that it could be psychological, but only if medical examinations and tests have found no physical cause and the source is not anything but psychological or psychiatrical.

When a diagnosis is made that the pain is psychological, it doesn't mean that the pain is "all in your head".  The pain being felt is very real and in some cases can be debilitating.  You cannot just tell yourself it isn't real in order to stop the pain from being felt.

If the pain has a psychological cause, then therapy will be needed to deal with it.  The therapy will enable you to discuss the issues affecting you and enable you to live your life the best you can.

If the problem is not psychological, although psychological therapy will not deal with the pain, therapy can also help with pain management if the problem has been a long term problem and causing stress, depression, anxiety or other psychological problems.  There are also complementary therapies which may help with both psychological and non-psychological problems.
