I had contracted legionella last fall. since then i keep headaches that run down the back of my neck and keep my neck painfully contracted.

Post-legionella prob: After recovery from Legionnaires' disease, you may get symptoms such as tiredness, poor concentration, cough or mild shortness of breath. These may take several months to settle. from http://www.patient.co.uk/health/legionnaires-disease-leaflet neck contractions may be another health issue and you should visit your physician
