Hello
Thanks for the concern
As you are with soft ware company may be need to work on computer for long time sitting in same posture ,neck down to see at the monitor for long time. You will have neck,eye and
severe back pain.
To avoid or to get relief:
See that your chair is supporting your back and neck while working.
Hands are well supported.
take yoyr eyes off every 15 mins.
stretch your legs and hands every half an hour.
Rotate your necck side and up and down (neck exercises)
stand up and take five mins walk in the office every hour
small exercises like rotation of ankle and wrist, strech outs every hour will help
try to keep your back straight supported by a good seating arrangement.
You need to follow these routinely in long run.
If still pain persists can consult an orthopedician for needful opinion and can go for
physiotherapy.
Hope i have tried to answer
