  There are various causes of a headache, and as you mentioned, previously it was associated with tonsillitis and then diarrhea. While headache is a feature in these conditions, it is possible that it was not caused by any of these problems but instead exacerbated during these periods. Only your doctor will be able to advise you further based on the results of the tests conducted, your past medical history and significant clinical findings.
  As you would have read on this article on constant headaches (http://www.healthhype.com/constant-headache-causes-of-persistent-continuous-headaches.html), there are various syndromes that can causes these episodes of headaches which can then be persistent for a period of time. We cannot suggest a treatment without knowing the cause which is the same dilemma that your doctors would be facing. It may be advisable at this point to see a neurologist who will run further tests and assist you further.
  Note from editor : Please do not post the same question more than once.
  Right now you are not experiencing any other symptoms apart from the headache so it is difficult to guide you further without relevant diagnostic investigation. It is worth noting though that neck muscle spasm is still one of the most common causes of a headache even though there is no obvious neck pain.
