Hi all generous docs here !!!

m having a very strange and unidentified kind of pain /headache in my scalp region....
This all started when I joined my 1st job.
my current age is 24....
I'm a software engineer so I need to seat in front of computer for 8-9 hrs daily...
The very first symptom was stress and sever headache in the evening daily...
this headache continued for 6 -7 months of my 1st job..
then I changed my job after 10 months...
when I joined 2nd job in initial 4-5 months there was very little stress so headache was absent. But when we had little pressure headache /(pain in scalp ) agani started...
this time it was different ...
The pain was 1st in frontal area of scalp .....then the complete occipital area...
now i have complete 1.5 years of my 2nd job...
Headache still exist in sever form...
Now the pain is in face bones also..
I'm having pain in my tooth roots also when I get stressed...
since when the headache has started m also facing problem of hair fall..
i feel pain in scalp mostly in the region where veins are passed..
when I exercise or plays sports of my interest I feel relief from stress and pain .. but its temporary..

To diagnose this i have done CT scan.. n have consulted to many doctors...
but nobody was able to resolve this issue...
all docs conclusion was..this is because of seating in front of computer for long hours and getting stressed because of that.

My eye power is -0.25 for both eyes ... (cylendrical)....

1 more thing to add..
this headache gets triggered when I seat in front of computer/TV within 30 mins pain starts...
