Blebs and bullae, which are large blebs, do occur with cigarette-smoke induced emphysema and are likely to cause recurrent pneumothorax with lung collapse. They can also be congenital or inherited, and these are less likely to burst. Talc-treated lungs can cause pain for years after the procedure, but if done effectively, the chance of recurrent lung collapse on the right should be markedly reduced and the nurse's estimate of 10% is reasonable.
The likelihood of collapse of the left lung will be dependent on the number, location and size of the blebs or bullae. A pulmonary specialist should be able to provide an estimate of the likelihood of this happening. Some experts might recommend waiting for the first lung collapse on the left but if the likelihood is deemed to be high, pre-emptive surgical treatment of the left lung might be an option. We can't speak to that likelihood.
