Pain & able to feel the implant. Any suggestions?

I had breast implants and an uplift in march 2016. I've just been on holiday and since coming home on Friday I've had pain in my right breast and I can feel the implant. I spoke to the clinic and was advised to see my GP who has given me a course of antibiotics due to having lots of mosqueto bites. I've still not got feeling back in my right nipple.
