Hi,Dear,Thanks for your query to HCM virtual Clinic.
I studied your query in all the details put forth by you.
I understood your health concerns.
Cause of the health problems you queried-
There are many causes of the lump in the middle of your back-like Sebacesous Cyst( with a central punctum or pit)/chronic Boil with subacute/asymptomatic lump/Epidermoid Cyst/Fibroma/
Lipoma etc.
As the clear fluid came out of it with bloody liquid coming out later on, it is to be worried and needs to be ruled out for the
tumor possibility and Hence I would advise you to consult ER Surgeon.
-Cause of such a lump which got sore after rubbing, seems to be Sebaceous Cyst ,which got clear fluid from the rubbing trauma with blood in it,which caused clear fluid with blood in it.
But it is necessary to rule out other causes of such back lump.
Also I don't have any first hand information or a photograph of the part.
So I suggest you to consult ER Surgeon,who would rule out other causes and would treat it according to the cause of this sore lump on the middle of the back.
Remedy-
So till the time you consult ER Ortho Surgeon and get his definitive opinion after above investigations,DON'T WORRY AT ALL but you need to be worried as it would complicate into some infection and other problem associated with it.
In the mean while,
Cold Compresses to reduce any swelling rise.
Take Anti-inflammatory drugs from your family doctor
And act fast on the above suggestions,which helps you to plan treatment with your ER Surgeon.
Hope this would resolve your query with full satisfaction.
