Thanks for your reply Mark.

I have been working 4-5 hrs/day after a week of my injury. Things were not improving and headaches were getting worst so took completely off from work last month, will join back next week.

I havent kept a general as such but yes, taking propranolol for headache prevention which helps reducing headaches 3 times/week. Still very sensitive to multiple noices, light and multitasking which is needed at work.
