I have severe anxiety and muscle tension as well and i had the smg because of back problems and was.told nerves were fine?

If your: EMG is fine and your nerves are fine then theis cold tension is from stress and anxiety. You should consider exercise to relieve tension and also seeing a therapist for other coping mechanisms so you don't take everything out on your body. Talk to your prescriber of your Paxil (paroxetine) too.

See a doctor: There's many causes for anxiety, such as chronic pain, bipolar disorder or thyroid problem, etc. I suggest you see your doctor get a full exam with psychiatric evaluation and blood test to find the exact cause. There's medication to treat it.
