Hi, I have had a metallic taste in my mouth for the last few days, headaches for at least a week daily in the morning and today severe neck pain. I am unable to turn my head to the right side, and feel extreme pain and light headedness if I accidently do look to the right. My right arm feels increasingly sore, like I ve been doing alot of exercise with it. Also beginning to get some numbness on the right side of my face and ear ache in the right ear. Panadol is not helping at this stage. Any advice gratefully recieved.
