Hi,Dear,Welcome with your query to HCM.
Studied your query in full depth of its details.Reviewed it in context of your health concerns.
Based On the facts, You mostly seem to suffer from-
2 seperate entities-The lump?
Lipoma / Sebaceous Cyst- in the lower back seems to be with ?either Muscle Catch from
sprain in the lower back, or from neural compression of acute nature with change in spine positions and maneuvering required in day to day movements and work.
or it could also be due to the Neurolipoma which gets triggered with some movements or trauma to the lump
The other lump in the armpit - is mostly from Furunculitis.Other causes like related to nodes/ or the breast,need to be ruled out by
Second Opinion from Surgeon .
X-ray spine and FNAC
Biopsy would resolve this issue of lower back lump.
Hope that ,This reply would help you to plan further treatment soon with your treating doctors.Best of Luck and early recovery.
Welcome any further query in this regard,which would be replied in next
session.
Good Day!!
