Constant diziness. Ar are interrelated?

I have been diaognised with migrane.when before four months i had migraine attack for the first time,taking prescriped medicines for around a week immediately relieved me.then again after a month and ahalf or so,i again had those headaches and unsteady dizzy feeling.then recently i visited cmc vellore,around a week ago and after examination was prescribed 40 mg propanalol and flunerizine.the general medicine consulatants also referred me to an ent specialist who diagonisedme with allergic rhinitis prescribing allegra m tabs and nasal spray.now i m on a one month prescription.i have been taking those since six days.the headache has reduced in intensity but dizziness remains.my jaws and neck also feel stiff. my question is should the medicines by now have eliminated my dizziness or if i need to wait and watch.and if the migraine and AR are interrelated?
