thanks for writing to H.C.M.
I have gone through your query regarding swelen lymph
nodes on head and neck along with red bumps which are painful.
Since the bumps are painful and are giving tingling sensation
it suggest infective nature of bumps. Because of infective nature of bumps lymph nodes of that area are enlarged and this is doubly confirmed by response of treatment taken in the form of antibiotics and anti infllamatry.
I am suggesting you to please continue the treatment and remain in touch to your treating doctor.
