I would say I ran about a mile-ish in under 15 minutes, which is very slow. I'm overweight and out of shape, so I was not surprised to feel sore after it. Although, many other people are not sore, it's just me. The day after that we ran again, this time I did worse, because I still didn't heal fully. I'm not sure if I should keep pushing myself, I didn't have gym today, but I'm still in pain. Walking down the stairs is the real difficulty, I can't do a squat without it hurting. Pain is normal, but I'm not sure if I should wait to heal.
Getting a feel for what is normal soreness, and what is an injury developing is a difficult and important skill for a runner. If you are new to this, then build up distance slowly.
A few general notes that may help to tell the difference between soreness that's part of normal muscle (etc) development as part of exercise, and what is an injury developing:
- If the pain is extremely sharp, stop immediately
- If the pain fades as you warm up, it may be fine to continue
- If the pain is in the same place every time you run, and gets worse each time, then it's worth trying a longer gap between runs.
- If the pain is in the same place after each run, and gets worse each time, then it's worth trying a longer gap between runs.
Nothing to be ashamed of at all, your body simply isn't used to it.
Here is a reason you can tell your teacher.
You have shin splints and let him know about the pain that's been getting worse when you run.
Have a parent write a note saying the this and stop by the your gym teachers office or you can drop it off in the morning at the principals office and ask them to give it to your teacher.
If the kids ask why you're not running say you have a "bone bruise" and your doctor said not to.
Below is a good article you can show your patients that talks about what can cause that. You can even print and bring it your next doctor visit if you want.
This question is very broad, almost too broad.
It very much depends on how much you exercise and afterall, only you can really judge how exhausted you feel and whether you should exercise.
It's okay to go running with during some muscle soreness, in fact it's a good thing to do as it helps to get the blood flow going. As long as it doesn't physically hurt so much that it causes you pain, then I don't see why you shouldn't be able to run.
