Dear.
The muscles may be sensitized.
Kindly look up pictures and videos on ergonomics of sitting which will tell you the scientific ideal good sitting posture, hence you can correct your sitting style appropriately. A physiotherapist trained in ergonomics can help you with this as well. If after correcting the sitting style your issue doesn't subside as much as you want then meet a McKenzie physiotherapist and get your lumbar spine evaluated and get appropriate exercises for the same .
Wishing you happy health.
