ibromyalgia
"I didnt have a headache while taking Savela (I could only take it for 5 days due to severe side effects), but Savella didn't work for me. I experienced a rapid heart beat, chest pain, painful urination and stomach pain. I was only taking 50 mg/day. 
My heart beat went from mid 60's-70's to 105. My blood pressure was changing constantly."
