Hi Sue, I struggled with rather severe pain after my SNB and also developed cording (a tight band under the armpit) but the wound itself healed with no oozing problems.
My SNB pain was so bad and i had limited arm movements for several weeks but i got through it eventually by lots and lots of stretching exercises.
I honestly thought i was the biggest wuss because other ladies had breezed trhough the op.
Hence my apprehension of full ANC op 6 months later, but this was a breeze! I had no pain really and stretched through my exercises quite easily.
When I questioned the BCN about why id suffered so much after SNB and not after the 2nd op, she admitted they'd probably damaged nerves after snb.
