Welcome to the forum. It is nice to know that your CT Scan
, sugar and blood tests are normal. Heaviness in the head that you are experiencing can be due to your long hour work on PC. You should get your eyes checked. Hope you have the glare of your PC adjusted to suit your eyes. Take short breaks whenever you get time. It will relax your eyes as well as head. Do eye muscle exercises
as soon as you get time or between work.
Heaviness can be due to incomplete sleep, inadequate rest. Take proper sleep, get a comfortable mattress. Constipation
often causes heaviness in the head, keep yourself well hydrated, keep bowels clean. Take fiber rich food.
Consult your treating doctor, get an X-Ray PNS done to rule out sinusitis
. You should get treated for it if radiology shows a positive report. Home treatment for sinusitis is steam inhalation. Partially the heaviness in your head is due to the ear problem. Get treated well,take care.
