Pain and stiff neck with Pristiq
I have been taking 25mg of Desvenlafaxine (Pristiq) for just under 5 weeks. I've had quite a few side effects including, inability to sleep at night – sometimes I can sleep early in the morning or catnap throughout the day, anxiety, nervousness, blurry vision, sweating, slightly increased heart rate, and a stronger beat with one incident of extremely fast beating that only lasted about 8 beats. Some of these have abated a bit, the heart rate is disconcerting. However, about a week ago I woke with a very stiff neck and pain in the back of my neck radiating up into my head. Today this was worse and I am unable to turn my head without a lot of pain. There is a feeling of tightness in the upper back of my neck and head. Has anyone else experienced this? I've left messages with the nurse that prescribed it but I have not heard back. I'm ready to ween myself off if this has not gotten better by tomorrow. Thanks in advance for any feedback.
