I am a 61 year old heart disease woman. I just had a sono and Nuclear stress teat and everything was great. I have been very sick lately with ear infection, sinus infection, bronchitis, UTI, and just 2 weeks ago diagnosed with Whooping cough. For the past week I have developed neck pain and stiffness. I also have confusion, disoriented, very fatigue, headache and SOB. I have an appointment with mt pcp. But could you give me any idea what I could have now. My neck pain is so bad it keeps me up all night.
