Soreness vs Pain
In order to make physical improvements, your body needs to be pushed to an appropriate level where gains can occur.
Each person's body has a different activity threshold dependent upon many factors, including age, baseline strength, and participation level. Remaining on the safe side of your threshold will result in muscular soreness. Exceeding your threshold will result in pain.
After activity, muscular soreness typically peaks 24-72 hours after activity. This is the result of small, safe damage to muscle fibers and is called Delayed Onset Muscular Soreness (DOMS). During this time, your muscles may be tender to touch and feel tight and achy. Movement may initially be uncomfortable but moving and gently stretching your muscles will help to decrease soreness. During the few day period that you experiencing muscular soreness, you might consider performing alternate exercise activities in order to give your sore muscles an opportunity to recover while strengthening other muscles.
In contrast to muscular soreness, you may experience pain during or after performing exercise. This may feel sharp. This pain may linger without fully going away, perhaps even after a period of rest. This may be indicative of an injury. Pushing through injury can worsen the problem. If you feel that your pain is extreme or is not resolving after 7-10 days you should consult with a medical professional.
