Hello dear, Most common cause of persistent headache with feeling of heaviness,while you are awake is TTH(Tension type headache),which is a stress associated headache.However,very frequently in clinical practice migraine is confused with TTH.Sometimes both may overlap.Migraine is typically episodic.hemicranial,pulsatile(though you are having pulsatile headache,but TTH may also have it)headache,which is precipitated with any triggering factor like cheese,coffee,smoking,bright light,loud sound,stress,lack of sleep.Migraine can be associated with nausea,photophobia(headache increased with bright light),phonophobia(headache increased on talking or with sound) or some visual abnormalities(like seeing zig-zag or flashing lights,half words or alphabets).You may have TTH or migraine ,possibly in that order.Burbs have nothing to do with it.In TTH drugs like escitalopram or amitriptyline are useful along with some mental relaxation techniques.Migraine can also be effectively managed with medicines.You need to visit a neurologist for this.I hope it helped.
