For almost 2 weeks now, i have been waking up with a heaviness in my head. It goes away for sometime and then again there is heaviness and at times it results in headache. I take disprin at times to overcome the headache. I do have a work schedule which involves sitting in front of a laptop constantly. But this heaviness in head has become a regular thing since the past 2 weeks. i have also got my eyes tested and the reports are fine. Please suggest what to do
