I had a spontaneous pneumothorax January 2010 and am now 15 weeks pregnant. I had to have operation to fix lung (bullectomy and pleural abrasion) and still get some pain from it but this has definately increased over the last week. I'm starting to dread getting bigger and the baby squashing my lung. Just wondering if anyone has any experience of this so I know what to expect? Midwife couldn't really tell me. Thanks.
