Possibly: Long term bed rest can lead to loss of muscle mass. In the legs, muscles function to squeeze blood from veins to the heart. If there is lack of utilization, it would take few seconds for the blood pressure to normalize and the dizziness to dissipate. If dizziness lasts longer, get further evaluate. Common cause includes dehydration as well.

Yes: Prolonged bed rest can lead to dizziness when standing up. It will take your body several days to become adjusted to changes in position again. Make sure to drink plenty of fluids, and change positions slowly until you feel that the dizziness is better.
