Is A Revision Needed?

Hello, I had a BA back in 2013 and originally had 185cc unders placed. Due to complications, I had to have them changed four weeks later and as a last minute decision decided to go slightly bigger with 215cc HP Furry brazilians (10.2 cm width). I have regretted it ever since. I am VERY petite (5'2 or 158cm and only 39 kg or 90lbs) and had a BWD of approx 9.75cm. I am so worried that the size I decided to go with (215c in the end) is too big for my very small frame, even after three years. I still get dull aching pains around the implant edges and incision lines on both sides that can last a good couple of days before they go away (is this normal, or is it possible my skin is now just hypersensitive?) and I can feel them under my skin. I am seriously considering a revision, but of course the cost is something I need to think hard about. Do you think it is worth it to go back to 185cc? Will it make that much difference? I am self conscious about the size on me (I don't wear a bikini) and worry people think they are obviously fake given my small size. I went from a completely flat chest (think ironing board flat) and now measure in at 8C if I can find it. I'm so worried and unsure of what the best thing to do is.
