HI,Dear,Thanks for your query to HCM virtual Clinic.
I studied your query in all the details put forth by you.
I understood your health concerns about the treatment for 
earlobe lump.
Cause of the  lump lower half of earlobe -
The USG study reviewed and means -that the lump is of Chronic 
Cellulitis with no active infection but with low grade inflammation.
Treatment -
As there is no infection, the low grade infection could be conrolled by-
-Hot fomentation,
-Infra Red lamp 
radiation treatment if need be.
-
Voltaren Gel locally.
-Tab Serropeptidase 1 mrng/ 1 eveingn x 5-10 days
-Tab 
Zincovit to expedite the healing.
This would help you to plan treatment with your ER surgeon.
Hope this reply would satisfy your query and would resolve the worry with it.
