I've noticed in the last couple of months that I'm getting odd little bruises appear that don't seem to have been caused by anything. They take 4-5 weeks to go and remain dark purple-ish in colour which just fades as they disappear - not the normal yellow/green spectrum you'd expect from a trauma bruise. Health wise I am generally okay - have hypoparathyroidism which I've been on 50mcg Thyroxine for since I was about 14 - get tested every year and dose hasn't increased yet... I'm on the Depo injection for birth control, and I take Symbicort inhaler as I was diagnosed with asthma (but I don't get any symptoms). any ideas??!! I am 27 years old, 5'6" and 202.5 pounds (I know I am obese) but I am active and do minimum of 4x 1 hour walks a week at just over 4 mph. Thanks
