I am a 39 years old male from India. I am suffering with a severe headache from last couple of days. The headache originated from the frontal lobe but now it is spreading over the entire head (in front side as well as in the back side). My BP is 124/84 and Pulse Rate is 76 but very fibble and occasional arrythmia . I am also suffering from occasional lightheadedness as well as dizziness but those spells normally come and go. There are sometimes sudden pain moving through my left arm for only a few minutes. I am also a patient of intra-ventricular conduction abnormality and severe sinus bradycardia which sometime causes breathing trouble. I am taking Clopitogrel 75 mg. OD, Carvedilol 3.125 mg. BDPC and Clonazipam 0.5 mg. OD for around the last three years. Are my problems a serious one?
