Diahn,

I really dont know how you know when it gets in your blood stream., I went to the doctor, and he looked at it, and said it had gotton in my blood stream. I geuss it gets in your blood stream only if you are allergic to it. If you have a rash that is still there, and you keep braking out in new spots, you most likely are allergic. The doctor told me that most people get the rash, and start clearing up a few days later, but some people need some help, they cant get rid of it on there on. My symptoms was.. I had (and still have) blisters and rashes all over my legs, arms and stomach, that was spreading more and more each day, I can not sleep at night from all the itching! I just wasnt feeling good at all, all over. Is your's clearing up any at all yet? If not, you probley should call your doctor. He can give you a shot to help. I have not had relief yet, I had mine yesterday, but they are already beginning to dry up. Good luck! I would like to know how you are doing. I will check back tomarrow.
