Removal of bio fibres. Please help!

I got 500bio fibres implanted in crown area in april last year. But since then i m getting repeated infections there alongwith light bleeding and frequent ache in the scalp skin. I hav taken antibiotics for 2 3 months constantly as prescribed by the doctor and intermittently also.The infection ceases during medication but returns after i stop antibiotics.I hav visited the doctor who did the implants many times.Earlier he kept suggesting me omniderm or bethnovate c bt when i insisted 3months ago that the pain and infection is more frequent now they removed some hairs.Bt after a month, the infection was there again.I again visited them.They injected betadene in my crown area and removed some more hairs.Bt after 20 days the situation was the same, rather more painful.20 days ago, I visited thm, that tym again they injected betadene and claimed that they have removed all hairs, including my own natural hairs, from my crown but in last 4 5 days, i am again getting infection.Please help
