I had a full body medical test for my new job in Kuwait, and it was normal at first test but when I went for the final test after like twenty to twenty five days then the report said that I have bubbles in my blood. I'm not sure that they were honest about it or it was just a threat to earn more money. But I want to know that why bubble comes in blood, and the effects in body because of that. And is it normal ?? Please help me with the solution
