Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain headache and pain behind the eyes can occur due to a number of common causes like Sinus infection or sinusitis, Meningitis, Encephalitis, stress and panic attacks, skipping the meals, thrombosed veins, arterial tears, at times dental and ear infections etc can also lead to headache and pain behind the eyes.. You should consult a General Physician or a Neurophysician and get a comlete evaluation done.. He can doa clinical examination, take your detailed medical history and advised investigations like MRI Scan,x rays, CT scan, blood tests etc to rule out the exact cause of the problem and treat you according to the cause.. Once the underlying cause will resolve pain will subside.. You should continue taking painkillers like Ibuprofen or Acetaminophen as of now to relieve pain.. Do meditation and breathing exercises to relieve stress. You should take a nutritious diet, drink plenty of water and also abstain from alcohol and excess tea and coffee,, Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
