Hi, this is Dr. Ramana. Based on your complaint of left-sided headache, you did not mention your age or profession, which are important factors in assessing your condition. Left-sided headaches, or headaches that occur on one side, are often caused by migraines. Migraines can be triggered by factors such as work-related stress, lack of sleep, irregular meals, and stress in general.

If you are in the software profession, these triggers could be particularly relevant to you, as the nature of your work can lead to poor lifestyle habits, such as irregular sleep and meal patterns.

Migraines can also cause symptoms like sensitivity to light (especially daylight) and sound, which can worsen the headache. Watching TV for long periods or using your phone late at night can also aggravate the condition.

Since you are experiencing migraine symptoms, I suggest you take the following steps:

Take prescribed migraine medication as advised ie, Napra-D 250 mg morning and night for five days.

Combine this with relaxation techniques such as yoga to help reduce stress.

Follow a healthy, balanced diet rich in fresh vegetables.

Remember that a CT scan is not usually necessary for diagnosing migraines unless there are other specific concerns, MRI would be more helpful in such a situation not CT

Please monitor your symptoms to see if the headache subsides or continues, and based on that, you might need to visit your physician who can evaluated further and adjust your treatment plan accordingly. Thank you
