Dear Doctor, Suddenly he got a breathing problem. He went to hospital and he used some medicines also but there is no use. So again doctor suggested for abdomen test, 2d echo test and some other blood test.In echo test we came to know that there is a blood clot in heart so treatment has started for him by injection but doctor said there will risk in that .if the blood melt there itself means there will no issue or else if the closed blood is flow down to any part in the left side of the body then that part won't works and also there will be a chance to go to brain also. So that makes us to be tense. Please tell me is this a serious problem .we are feeling very tense.
