Light headed weird feeling

I know you guys aren’t doctors. I plan on speaking with my doctor but I was just curious if you guys have experienced this before. You know how you get light headed when you stand up ? Well at work, I stood up then 30 seconds later, I got the light headed feeling, like I do a lot. After a few seconds, it usually goes away but this time, it was worse. My head felt heavy. I couldn’t concentrate, my heating was a tad muffled. It lasted for about a minute. Has any one ever experienced this ?

Ps I’m not pregnant
