Is it worth contacting a therapist with mild symptoms?

Yes.
Complaints such as discomfort, fatigue in static situations (sitting, standing for long), changes in posture, etc. there may already be signs of local overload, which means that the static balance of the body is beginning to upset. If you visit a chiropractor when such signs appear, you can restore balance with 1-2 treatments, learn what to look out for during daily workouts, and prevent more severe symptoms from developing. It is recommended that you go for a treatment every year without complaint, especially for a person who is exposed to a long-term unilateral load on a daily basis.
