Can Mastitis and Blocked Ducts Lead to Capsular Contracture?

I had implants in 2004. 6 months ago I had my second daughter and developed a blocked duct and mastitis in my left breast from feeding. My breast is still swollen and painful, an ultrasound showed that the implant was intact. My daughter is now 28 weeks old, last week I returned to my GP, in her opinion my implant was perhaps tethered, although PS didn't agree, I have a further app in 2 weeks.. My implants are PIP and I am going to have them removed. Could the infection have caused contracture?
