Just to add in my experience, my skin has always been soft and prone to bruising and poor wound healing, but it seems to have got worse in recent years (since I beacame menopausal).
When I had my last surgery back in January, the op was nearly cancelled on the day as I had an open cut/sore on my big toe that had been there for over a month. It has just about healed over now but you can still see a red scar where it was even now.
A week after my op I was doing some trigger point therapy on my leg (as my physio had instructed me) and where I pressed too hard, my fingernail broke the skin - that was over 3 months ago and the skin still has not healed over.
My surgical scars are also more prominent than other people's I have seen who have had the same ops as me, and when I had my Hysterectomy the wound split open in early recovery and is still very wide and raised - nearly 2 years after the procedure!!
I should point out Hannah that I have been diagnosed with EDS so my skin problems may be more extreme than yours. We are all different so I don't want to over worry you - this is just my personal experience.
