Recently I was diagnosed with typhoid. I was have fever that was ON and OFF throughout the day and very severe headache continuously that continued even after taking Crocin 650. Now I have completed my typhoid medications still I have pain on the back side of my head where the neck starts and it is continuing till the back of my eyes. The pain is not same every time it increases when I move my head and it's not there at all when I am still. What could be the possible cause?
