I was sitting and looked down at my toes and they were dark purple. I've never experienced this before. I am in good health other than hepatitis c which I've had for 35 years. I ran 4 miles on my treadmill this morning and don't have a breathing issue unless I'm walking uphill. I'm a 60 year old woman, I take very good care of myself... eat right... exercise everyday...and get plenty of sleep. No symptoms like fatigue. I had hormone implants 3 months ago which was new for me. I've taken hormones but this procedure is new. The implant consists of testerone & estrogen & I orally take 400mg of progesterone at night. I love the way I feel and my sleep is wonderful... no night sweats or flashes. I'm 5'3'' & weigh 128 lbs. I am a hairstylist and work full time standing on my feet.... I've done this for 42 years.
