hello and welcome to HCM,
The small lumps which are spreading could be boils
which are common in the ear lobe area.
They usually subside with no treatment in a day or two. Just apply any antibiotic ointment and do not try to touch, meddle or squeeze them.
If they are increasing in size then you may have to consult a doctor who may prescribe antibiotics, pain killers and stronger ointments
If the problem recurs then do a complete blood profiling with special emphasis on sugar levels.
If you are using ear phones or jewelery, make sure they are clean and do not share them with others.
hope this helps
Dr Sriram Nathan
