在arm和was间加个which.blood suddenly started flowing out from my right arm was so red that I was scared.实际上是两句1.blood suddenly started flowing out from my right arm.
2.my right arm was so red that I was scared.再加个which改成定语从句就行了.

and then blood suddenly started flowing out from my right arm was so red that I was scared不对，这里有两个谓语了 started was 。去掉was

arm 后面加上 ＂. It＂
