So, last night I had these issues, like I lie down and my head hurts, feel lightheaded, feel a sense of fullness in my head, particularly the lower back part of my head. Felt as if I was going to die, like the blood was not getting in my brain. It was so scary!!! It has happened from time to time in the past month or so. Is that a neuro issue or a cardio issue? I hate the vagueness of these symptoms!!!! I thought once I got back on the florinef that would go away, but no, it is not! I have been on the florinef for about 6 days. Also, since yesterday my left eyelid is all twitchy. I don't understand why my body was perfectly fine in December 2009 and then it just flipped a switch and became completely horrible. Ineed a good cry, this just *****. The worst part is my cardio swore I'd get better. I'm not getting better. Sorry, I can't cope with this today.
