question on pain

[n2euro]

Ive been cycling OstaI on and off since December. Ive gained a solid 20 lbs. Since January and never had any issues with pain until now. When doing curls i get severe forearm pain that feels like it is coming from in between the bones. It almost feels like my arm is going to snap like or someone is bending the bone. It also hurts when i let go of the bar. Any ideas?

I might also mention ive never taken anything other the Osta before and never made gains that fast. Could this be from growth?
