Have you had you blood pressure checked laying then standing.? It must be a postural drop. Have you seen your GP about it..?

Unlikely to get much feedback here, unless you also have lymphoedema - Kentlymphatics gives sound advice - see your GP if you are concerned about these symptoms.

You must see your GP asap. No one can diagnose on here - but this must be checked out. Are you on any medication? Anything for treatment of high Blood pressure? If so contact the nurse for Blood pressure check immediately - otherwise see GP.

As an initial guess I'd agree that you need to have your BP looked at
