I have an unidentified repetitive stress injury (RSI) and doctors have universally tried some treatment, failed, then told me I'm simply working too much. This happened after I stopped all my hobbies and took a 30h/week job (flex time, with frequent breaks). The identifier RSI lends itself to this diagnosis.
When the symptoms show signs of improving, the doctors immediately conclude "Well, you're getting better now, so just continue as you are now and we'll consider this resolved." An acquaintance suggested I overwork myself before going to the hospital so I don't risk being dismissed by a temporary improvement in my symptoms.
I've had several sprains and a broken wrist that were resolved quickly and without complications.
I have a friend who has struggled with increasingly severe "RSI", for lack of a better diagnosis. He even had carpal tunnel surgery on both hands. In the end he went to Mayo Clinic and they diagnosed him as having fibromyalgia. This was pretty recent so he hasn't had much time to experience the effects of the recommended treatment program, but it may be something for you to look into.
NB, but AFAIU fibromyalgia is a condition that's not ruled in, but is made by exclusion -- symptoms not otherwise explained. Mayo's site gives "widespread pain for more than three months -- with no underlying medical condition that could cause pain".
Several of the general / vague symptom conditions are similarly diagnosed.
