Welcome to Just Answer:
It is likely that these are lymph nodes or inflammatory nodules due to underlying infection or autoimmune
inflammatory connective tissue or collagen vascular conditions. This would likely resolve with time if due to temporary viral
, bacterial or allergic reactions. However, to determine the specific cause and better direct treatment, I suggest that he follow-up with his doctor for closer evaluation with tests including complete blood count, possible biopsy and testing of the lumps, chem-8, ANA, ESR, C-reactive protein, serum calcium levels, and ANCA panels. Treatment will be directed at specific cause based on the results of the testing.
