Hi, I had 550cc silicone implants 9 years ago, over the muscle and went from an A to an F cup. I regularly exercise and have always found such shortness in breath ... it scares me sometimes. I find it so difficult to breath and get my breath back and was wondering if perhaps the weight of the implants are affecting my lung capacity. Is this a thing? Or am I just actually stupidly unfit...though I dont class myself as being so?
