When I stand  after sitting a while, sometimes I feel whoozie.  my arms and legs get shaky, my head feels funny, things get a little dim. But I fight it and it pass. But it feels like I am going to fall with no control of my body. It is not a spinning feeling, Im having a hard time describing it, but it feels like fuzzieness  and my legs want to give out nd my arms dont want to hold me up.
Hi, Thank you for posting your query. Based on your symptoms, you could be suffering from postural hypotension. This refers to a Chat Doctor.  This can be verified by checking BP in sitting/lying down position and then again in standing position. Are you using any antihypertensive medications? As some of them could cause similar symptoms. Finally, get your hemoglobin checked up, as low hemoglobin (anemia) could also cause similar symptoms. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health,
