I had a swollen lymph node in my neck 2 weeks ago; I asked my doctor about it and she told me to take Cefuroxime for 7 days then it disappeared, but after that I felt something in my groin, there was a swollen lymph node too, I went back to my doctor and he told me to take Co-Amoxiclav. Today is my last day of taking the medicine, but the enlargement of the node just decrease in size but it still there. Then yesterday, I felt a swollen knots in my outer thighs and inner legs, what might that be? Help me please. Now I have a painful node in the clavicular area. What might my sickness is?
