doctors of the BBS

This is an appeal on behalf of a very good friend and his wife,bit of advice really, she has been complaining of ill health and pain for a couple of years, she has been in and out of her GP and A&E countless times and they must be sick of seeing her almost on a weekly basis she is in her mid 30's. First of all she read somewhere that she thought she had a problem with her pancreas, blood tests and a £1000 bill for a private endoscope at St Anthony's revealed nothing , then she felt there could be other problems with her internal organs so he paid for her to go back home (South Asia) and have a full medical check up in one of the best hospitals in her capital, she paid for an MRI/CAT scan as well, again doctors found nothing , she came back to the UK and demanded another MRI scan which her GP granted her which again revealed nothing, she has had numerous blood tests nothing whatsoever has been found, she has been tested for Crohns/Parkinsons and MS and still all negative,she has had her womb tested as well its is really starting to get him down, only a couple of years ago she was the life and sole of any party now she cant even sleep in the same bad as him, she complains of pains all over her body on a daily basis, she has even tried medical cannabis, new age remedies! what I am thinking is that she possibly needs psychotherapy and another issue is can the human body produce so much pain yet not display any symptoms at all? I really wonder?
