How do I treat the chronic headache due to subdural hematoma and CSF leakage?

Hello doctor,

I am in my forties with type 2 diabetes. I was also diagnosed with subdural hematoma due to CSF (cerebrospinal fluid) leakage two years back and have had constant migraines since then. I have taken multiple CT (computed tomography) scans and show no sign of brain bleed, but I have tenderness in the temple and pain in the face and left arm. I cannot sleep because of the headache, and it feels like the blood vessels are making a sound in the head. I also get anxiety attacks sometimes. Also, I had to rush to the clinic at night thinking I had a heart attack, but the ECG (electrocardiogram) showed no sign of a heart problem. I am currently on anxiety medication for the past six months. The medications have helped me with my anxiety, but still, I am not feeling good. Kindly help.

Thank you for your reply doctor.

1. Subdural Hematoma was treated for CSF leak with a blood patch procedure and followed a few days later with a burr to drain the remaining fluid. Everything was successful, I have had various CT scans and one MRI scan, and none have shown re-occurrence of another CSF leak or bleeding.
2. I have continued to have migraine headaches post subdural hematoma. I have them very regularly and have become very accustomed to them. I have episodes that seem to last for weeks at a constant ache, and I have learned to manage to live with it. But sometimes, they get very intense and unbearable pain that I cannot work. I get anxious because of the headache, thinking if I have a recurrence of the brain bleed. I have constant pressure and pain regularly.
3. The pain is felt over the temples, forehead, and lower neck.
4. I feel heaviness in the head and throbbing pain in the forehead and temples. In addition, I feel nauseous, along with a headache. Also, I feel a ringing sensation in my ears.
5. I have a persistent headache.
6. I have been taking painkillers for almost three years.
7. I always feel nauseous.
8. I did not have watery eyes, but I sometimes felt wet in my ears.
9. When I touch the face gently, it still hurts lightly. Although gentle massage in the forehead also alleviates the pain. But on laying down, there seems to be no change in the pain
10. Also, I take Tablet Topamax 150 mg twice a day and botox injections every three months. However, this combination has helped me manage my symptoms to some extent.
11. I have poor vision without the glasses.
12. I have attached reports.
13. A few months back, my anxiety attack got so severe that I had to rush to a nearby clinic, not understanding what was happening to me. Since then, I have been on medication for the same, and the conditions are better now than before.

Kindly help.
