Neg biopsy follow up question

My skin and tissue biopsy for IBC came back negative. (Previous post) We were holding our breath. 

My incision looks good, however, I now have a dot on my skin that looks like a pimple almost but there is nothing in it.  The skin is a little flaky at the red point.  It is not very big about the size of pin top.  Those little plastic balls on the top. Maybe 1/4 in.  Doc said today that she thought it was from the adhesive of the bandage after surgery clogging a duct.  It showed up at day 3 or 4 after surg and has not gone down.  Neither have my nodes or the swelling.  (the swelling before the surgery)

My doc now has me on a nerve blocker medicine.  She thinks that maybe my implant is doing something to a nerve in the pectoral muscle or on the chest wall.  I think that since my biopsy came back negative Her thoughts are that I am all in the clear.  I know that they are not always right it really depends on if they get the right spot. 

My question is does it sound right to think that the implant is causing all of this through nerves.  I understand that if it hits a nerve then it causes pain.  If I had just pain then I would have no problem but would it cause the swelling (when the breast is swollen the nipple is flatter), swollen nodes, firmness of the breast, and the redness that comes and goes? oh and the red spot?

Sorry guys I have no one else to talk to abut this stuff and some of you are so knowledgeable.  Has anyone else heard of someone with these type symptoms being releived by nerve medicines.  Obviously, if the nerve medicines work then I will have the implants out and problem solved.  But really I think it is something else.  Any ideas?  I am stuck here with no second opinion and no where to go.  I keep thinking someone here will give me an idea then I can take it to the doc and say what about this? 

Anyway thank you for letting me vent a little.  I was crying in the doc's office today because I am so tired af all the pain and not knowing what is going on.  The pain is so bad sometimes that I am on Vicadin to dull it.  Anybody else in that much pain?
