Hole/Indentation in Bicep??

Recently my bicep started feeling sore and I haven't worked out in a few days so that wasn't the reason, but it was after I woke up from a night of working. I do physical work which sometimes leaves my muscles sore in the morning but when I went to flex my bicep it felt different, there was a hole or a line of indentation in it separating about 80% of my bicep from the other 20% (like a chunk got cut out internally). Whenever I flex it, it feels really sore, anyone know what this is?

Read some info online, and I think its just a minor tear, I don't have any sharp pains or anything really serious that was listed. Still going to a doctor about it.

I think its just a strain, no sharp pains yet and it doesn't look like it lost connection with my elbow. I can still see the tendon's connection with my elbow, so it isn't that bad, but I'm still going to the doctor.
