HI,Welcome with your query to HCM.
Based on the facts of your query,
In my opinion you need to check out the diagnosis before planning the treatment of your son's
biceps knot,with your Surgeon for a
Second Opinion.
Confirm the ambiguity of the cause of the lump.
Xray of the shoulder / and or / USG / CT Shoulder /biceps area and FNAC
Biopsy with Histopath study would fix the cause from your Surgeon.
There are many causes like -Sarcoid Granuloma/Fibroma/periosteal tumours/
Erythema Nodosum/ which need to be ruled out.
As the
fever /pain is not there,your case becomes more challenging and would need a team of doctors-Surgeon/OrthoPedic/Physician to fix the diagnosis.
Such a lump after proper diagnosis could be treated by your doctor according to its cause.
Hope you got the answer for your query.
Hope this would help you.
Welcome for any further query in this regard
Will appreciate writing your feedback review comments,to help the needy patients like you at HCM.
Good Day!!
