I have a cold tingly sensation in my chest cavity. feels like my heart is leaking fluid? have uti, seen a doc. cholesterol, bp and sugar is normal.

Maybe anxiety: If you told your doctor and your EKG was fine and your lungs were fine consider anxiety. It is a very common symptom of anxiety. Remember to drink lots of water for your UTI and if you did not discuss this with your doctor call back for a recheck. Feel better soon.

Odd sensations: It can be difficult to know what is causing odd feelings, and without a physical exam or one-on-one interview, giving a personalized answer is not possible. Be assured, however, that blood from the heart is very warm, and that a heart with a tear that leaks fluid into the chest is very rare, and occurs typically in an elderly woman in the intensive care unit who has just had a severe heart attack.
