Why do my inner thighs hurt after running?
Your inner thighs may hurt after running due to delayed onset muscle soreness (DOMS), which happens when your muscles are not used to the exercise. It is common and usually goes away on its own.
Explanation
After running, your inner thighs might hurt because of something called delayed onset muscle soreness, or DOMS. This soreness can happen when your muscles do something they are not used to, like a new exercise or running longer than usual.
Why It Happens
- Muscle Stress: When you run, your muscles work hard. If they are not used to this activity, they can get tiny tears, which can cause soreness.
- Not Lactic Acid: Some people think lactic acid causes soreness, but research shows it is not the main reason for DOMS.
What You Can Do
- Rest: Give your muscles time to heal.
- Gentle Stretching: This can help your muscles feel better.
- Hydration: Drinking water can help your muscles recover.
DOMS is common and should go away in a few days. If your pain does not improve, you should talk to a healthcare provider. Remember, it is important to listen to your body and not push too hard too fast.
