Hello My Name Is Antonio Franklin And Here Is My

Hello my name is Antonio Franklin and here is my dilemma. i seem to feel dizzy and light-headed when i stand and walk around for a short period of time. i am drinking water and eating but the symptoms still return. Also my skin seems to start feeling clammy and cold. i have to lay down most of the day just to feel a little better. At first i thought it was mostly a bathroom issue because i had a little trouble doing number 2 so i took some pepto bismal and i got a little better but dizziness continues. i don't know if this means anything but i suffer from severe sleep apnea but i also have a c-pap machine that i use, and my blood pressure runs a little high. I am trying to hold off of going to the hospital as i have no insurance but if it gets worse i just may have to go to the emergency room. Can you please give me some possible diagnosis on my ailment and what to do next? Thank-you
