I get things like that happen to me all the time but I've been smashed up multiple times in road accidents. Sometimes you have to rest it if it's serious other times if it's something minor you can train through it. Obviously no-one can diagnose you over the internet but it does sound a bit like muscle spasm (which can be very painful)
Protect yourself at all costs, there's no point trying to force yourself back into something when you're in pain, take as much time as need off and ease back into training when you start again.
Good luck bro, I hope you're back in action soon.
Ahh ok so I'm not alone on this, I have had something similar happen in the past but never this bad. It was strange coz I wasn't exerting myself at all.
I tore a muscle in my neck about 9 months ago, and the pain was as bad as that.
I think I will rest up again tonight, just to be safe as it's still a little sore.
I think your right and it's a muscle spasm or a bad know or something, I don't think it's too serious though :)
I will be back to it tomorrow
Take it easy. You're doing calf raises for a week per Dr. @steemmatt.
Oh damn how did I miss this comment, thanks doc ;)
