I had the exact same experience.
Numbness/tingling. Thought I was having a heart attack. EKG and CT scan. They say I have a pinched nerve but I just don't buy it. Did your neck pain go away after stopping adipex?
I was on phetermine for a year and so was my best firend. In the beginning I had some minor side effects like dry mouth loss of hunger, lots of energy. My firend had the same side effects but also developed insomnia. I thought she was crazy but after a while I developed insomnia and also had some chest pain and numbness in feet. Shortly after taking the pills I had a pulmonary embolism. Which is a blood colt in my lung. The doctors said that they have no idea how i could have developed it. So be very careful. I had great results I lost like 50 pounds in 3 months my friend lost 80 pounds in 7 months but I would be careful. By the way I gained the weight back plus more. So did my friend. P.S. My doctor preformed an EKG before giving me the pills.
I am taking Phentermine, but have had no side effects.
The pinched nerve could be causing the light-headedness along with the feeling faint. Have you felt any of those problems before the pinched nerve? if not, i'm sure thats what it is. I'm no doctor though.
Sorry! i hope everything subsides soon!!!
