Raynaud's Syndrome
"I started the nifedipine/Procardia this morning. About 4 hours later the rare side effects kicked in. Heart palpitations, dizziness, headache, and I was FREEZING. Even at 43 I still call my mommy. She wasn&#039;t thrilled I was going to take it anyway since I have perfect blood pressure. But she recommended laying on my left side. That did help even if it did take awhile for me to get warm again. The headache is still lingering."
