Hi it's a nerve irritation and needs evaluation by an experienced Physiotherapist. 90% of the times with proper and consistent therapeutic exercises nerve impingement becomes better and the patient gets relief.
Nerve impingement at such young age can be because of usage of wrong posture while doing daily work. See a Physiotherapist and learn ergonomics. You will definitely get better.
