Suggest Remedy For Swollen Glands In Neck With Lymph Node Infection

for 6 weeks now ive had swollen glands on the right side of my neck, this has caused excruciating pain, have taken paracetamol, codeine and ibuprofen with no avail, saw my gp 3 times, who first said it was muscular, then a lymph node infection, ive had 2 courses of penicillin, with no success, im becoming frustrated now that no tests have been done, also im a nurse and have been working shifts through this with no sleep due to pain, thanks
