Dear Rebecca, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Appreciate your efforts to give detailed description.
Clearly, there is no correlation of the blood reports and the lump.
It could be a lipoma
(fat tumour) if it is since childhood. On growth, it may be a little painful. It is totally harmless.
Rarely there could be rectus sheath myomas
or soft tissue
If a doctor can not reliably tell what it is by its clinical examination (as occurs many times), a surgical excision biopsy
is possible and removes all doubts.
Please consult a surgeon on this, if it is hurting.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this query.
Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
Good Luck! Thank you!!
