A word of warning, about Edema or fluid build up in soft tissue, is it can lead to ulceration and even fibrosis. The nature of extenders being used daily for prolonged periods with say, a head modification that leads to repeated fluid build up could give rise to these problems. Good health and circulation will help you avoid complications, but if you have blood pressure or cardiovascular problems be careful.
Off the shelf creams such as MSM, Vitamin E and Vitamin C creams have been used to ease these complaints.
I CAN, I MUST, I WILL!
