Hi Teri,
Like others said there could be many reasons for lightheaded & dizziness .. Besides what others mentioned , Do you have hearing / ear issues ?
Not only would i let the cf team know, i would go to my primary dr. & have him/her put all the pieces together to figure out the problem ASAP ..
Hope you feel better soon.. Take care & keep us posted <img src="i/expressions/heart.gif" border="0"> joni
