I has my surgery April 5 and two weeks post op I passedout at home twice. My doctor says for me to increase my fluids and i have done so, but I still can not feel like i did before i passed out. I have no energy and still feel light headed and dizzy. Will this pass..every one keeps telling me it will take time but I am miserable not being able to feel like myself. Any sugeestions on what this felling may be coming from?
