This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Indeed genuine concerns.
Swollen lymph nodes are not usually seen with GERD.
Hence, sore throat and swollen lymph nodes raise the questions:
1. Infection --viral like Epstein barr virus, or bacterial.
A throat culture is needed.
2. Autoimmune condition --Sarcoidosis or Wegener's granulomatous disease can affect the lymph nodes
3. Malignancy--given the history of low wbc count, and swollen lymph nodes, possibility of slow growing lymphoma is still there.
A CT scan of head and neck and a lymph node biopsy should be contemplated.
Please discuss with your hematologist.
It was my pleasure to help you today.
