What causes a tender lump on the neck?
Patient: three year old complaining of lump under skin on side of neck is tender to touch. When feeling it moves under the skin. Size is about nickle in size. No neck injuries ever. Just got off antibiotic for strep and a UTI about 5 days ago. Occasionally complaining of stomach hurting but not when using the bathroom.  No sore throat any longer.
