Hi, I Had Red/pink Eyes In Last Month And Used

Hi,
I had red/pink eyes in last month and used eye drops and ebastel (allergy tablet) after consulting with doctor. Then redness it cured and eye tiredness and eye lid pain occurred constantly and also started headache feeling in the lower forehead. I checked the eye power, it is 0.5 and also my eye pressure level is normal. Little dryness is there and taking eye drops for that.
Always I feel some pressure on my forehead and eyes. Last week took x ray of my head and doctor said there was no symptoms of sinus and prescribed some medicines for migraine.

Please suggest am I having migraine or any other problems?
