Tingling below tricep

When I stretch my left arm out, when triceps are extended, about an inch above the elbow I get this tingling sensation (not pain, and very targeted) that intensify as I stretch further. Fear strikes in and I don't stretch further..

Any idea what this tingling sensation means? 

Hi Yoon,

I would suggest to reduce the instensity and if it remains get it checked by a physio or other medical professional
