My right arm is sore roughly 24 hours after working out and it hurts to straighten my arm out.
Thank you for reaching out to us. Without examining your arm, we are unable to give specific advice or diagnose your pain. Since your pain began after working out, it may be associated with muscle fatigue.
Muscle soreness following exercises that you are not used to doing or that are more difficult than your normal exercise routine can cause delayed onset muscle soreness (DOMS). In DOMS, symptoms may begin the same day as or a day or two after the workout and can last as long as five days. The affected muscle(s) can be tender to touch as well as painful to stretch or use. Performing a cool-down after exercising may help lessen the severity of DOMS after a new or hard workout. For individuals with DOMS, it is generally recommended that they perform “active recovery” in which they continue moving and using the affected muscle in pain-free activities.
If your symptoms do not improve within one week, we recommend that you seek the care of a physical therapist, who can examine your arm and use the findings to create a treatment plan which will optimize your recovery and get you back to working out safely as soon as possible. Additionally, if you do not have a sore muscle associated with your symptoms, but rather pain at one of your joints, we recommend that you have your symptoms assessed by a physical therapist who can assess your arm and design a treatment plan to help you regain pain-free movement while also reducing your risk for re-injury.
