Blood in urine (haematuria) Introduction. Finding blood in your urine can be very frightening and must be investigated by a doctor, but it's not usually a sign of anything life-threatening.

An inside look at the structure of the elbow. #. Advertisement. Advertisement. The elbow is where the two bones of the forearm â the radius on the thumb side of the arm and the ulna on the pinky finger side â meet the bone of the upper arm -- the humerus. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.
The inner portion of the elbow is a bony prominence called the medial epicondyle of the humerus. Additional tendons from muscles attach here and can be injured, likewise causing inflammation or tendonitis (medial epicondylitis, or golfer's elbow).
