HI,WElcome to HCM with your query.
Based on the facts of your query,I would suggest you to consult a Surgeon,who is the right doctor to advise on treatment,as the information is very limited.
Treatment is a function based on diagnosis with good basic clinical information of the ankle and triceps lump.As your diagnosis cant be made,it would be nice to consult your GP, and Surgeon if need be.
There are many causes of the painless lumps in triceps and ankle area,which would be examined by your doctor and would be directed for further treatment.
Still from experience to name a few -
Painless Triceps lump could be Sebaceous
Cyst and a Surgeon would confirm by Surgical excision if need be.
Painless Left Leg lump above ankle on outside,could be Sebaceous Cyst/Varicsoe Vein.
Hope this would help you to plan treatment with your doctor.
Will appreciate your review write up and hitting thanks,to help needy patient visitors like you at HCM.
Welcome for any further query in this regard.
Good day!!
