Question

Ralph sustained a leg injury in a bowling accident and had to use crutches. Unfortunately, he never took the time to learn how to use them properly. After two weeks of use, he noticed his fingers were becoming numb. Then he noticed his arms were getting weaker and tingling. What could be his problem?

Answer 1

Ralph's radial nerve may be getting compressed

Step-by-step explanation:

Based on the information provided within the question it seems that Ralph's radial nerve may be getting compressed. This nerve, which is located in the armpit region, if compressed can cause temporary cessation of nervous transmission which is what causes numbness (as Ralph is feeling). If this compression continues for too long it can also cause permanent nerve damage.
