Pain and itchiness long after explant. Any suggestions?

I still have bruise-like pain, heaviness and itchiness in my left breast after explant over 4 months ago. There is no seroma, hematoma or other fluid anymore, the other breast is completely healed and about half a cup size smaller. The lightning-like, shooting, stinging pains never went away, they might be getting worse, it's hard to tell. Anyone know why this is not healing? Anyone have experience with this?
