Ok this hasnt happened in a while. i had this a lil while back, i would see starts after deadlifting or while pickin up the weight. well today i had that problem. I went for my 1 rep max i got it up decently, I didn't really strain that hard in my opinion. after I put the weight down i saw little dots or stars w/e u wana call them. I saw them for like 10 seconds than they went away.
What is this? and is it dangerous?
