Sick..

I have been having headaches or rather pains in my head.They didnt last long but it moves from veins to veins?different part of my head started to feel the pain?especially on my left side,near my deaf ear.I wonder if there's anything wrong wif me,forgetting where i had placed my hp.WELL,maybe I have seriously gone nuts.I hv seen my family doctor yesterday afternoon,he was asking how was I doing,and we laugh for a bit but when I told him I had been having pain,he turned serious.He said it might be serious as it could be caused by my long-term asthma(which i didnt koe there's an effect).He then further explained as I had received many treatments which are very strong which why i felt very exhausted each time I had an attack and this medicines sometimes could cause pain?HAHA....
