buldging not a lot and they are half a cm across in width but lines sorry for that type of stuff iam just concerned..

That sounds bizarre. Something is wrong! It sounds a bit like veins or arteries?
Talk to a doctor!

Your description is difficult to visualize, could be stretch marks, they look like what you describe, however if this is not what it is consult your doctor.

Are your glands swollen? It could be stretch marks developing or possibly an infection of somekind, consulting a doctor is your best bet.
