Hi froggietcu!
The original symptoms listed:
- headaches right behind the nose
- swollen lymph nodes
- difficulty concentrating
- fatigue
sound like ones I experience, and I don't have a runny or congested nose either. It is definitely allergies and the only solution I can find that helps at all is a nose spray, called Nasacort and/or Sudafed decongestant (the little red pill). Also, winter's are the worse. I wish you success in helping DH.
