Sir I have a serious question. My question is that actually my uncle used sugar machine (i do not know how many times with the same needle) and then his friend used that same machine with same needle (without changing that used needle) and then I used that needle without changing on my hand four times (i pinched that needle in my finger four times). Well I am just 18 and I do not have any sugar but I used that machine only to check. But then I came to know that it's a serious matter and it can spread diseases. And now I am feared that I will be infected with disease. I want to know whether I am infected with any disease or not. I do not know about health conditions of any of them except that they have sugar. Please help me please.
