Hello, Your history is unclear to clearly differentiate the symptoms But since you have said you had severe traumatic hits in your head in past, it may be a reason. Frequent heavy hits in head is dangerous, this is more common in boxers. There will be subdural hemorrhage, when pain is associated with impaired mental ability, memory it may be neurological due to traumatic injury. You need to consult a neurologist, he may suggest you to get an CT scan and for further information he may also ask you to take a MRI scan. Please try to avoid such kind of relationship or if it is not possible try to get counselling for both of you. Take care Bye
