Some people experience pain and soreness like symptoms right away and others wonder why they start experiencing pain the day after or two days after the work injury, but not right away.
It’s like when you go to the gym and exercise for the first time in months, but don’t experience the intense soreness until 1 or 2 days later. In the gym, it’s called DOMS (delayed onset muscle soreness), in a work injury, it’s due to the injured tissue going through the inflammatory phase of the remodeling process.
