What Causes Arm Pain After Trampoline Jumping Without Injury Or Impact?

What Causes Pain In Arms After Trampoline Jumps? I went to an indoor trampoline center last night..within the first couple jumps both my arms started to ache very badly as if i had broken all the blood vessals in them..i did not land on my arms at all a this time...there was no tingling or numbness..it has persisted over night till the next morning. I feel better tonight but im worried what this could be..nerves, blood flow?
