question: My husband who is 43 has been experiencing a host of unusual symptoms for the past 6 weeks. Tingling in head and arms, tightness in head, neck, and chest, insomnia, loss of appetite, high anxiety, frequent belching, sore throat, inflamed and sometimes swollen tongue, and a slight cough. A blood test showed elevated d-dimer. Chest x-ray is clear and CT scan shows no embulisms. What else could be causing these symptoms? I think it might be his wisdom teeth even though he doesn t have any tooth pain.
