My husband had stiff neck , pain on top of head, pain on the top vertebra area, nausea if he moves (throws up), dizziness . Is fine in the day - symptoms worse at night. It started some weeks ago with waking up with severe headache . Both doctors suggested sinus-related problems (he does suffer from infected sinus at times). Was given Litares, recovered, then symptoms reoccurred, given Litares again, and got better. However, night before last ended up in hospital. Blood tests showed negative, except white blood count raised, indicating infection. Was fine yesterday, but 4am this morning threw up again. We have dogs that sleep indoors, and he thinks it might be allergy . But so severe? (he is also type 2 diabetic, but under control.
