Feck I had forgoten about this stuf, Your missing "spontaneous pneumothorax
The question is whether it is actually correctly categorised as "Spontaneous" or "Disease-induced spontaneous" (which is not necessarily spontaneous). "Disease-induced Spontaneous" is a pre-defined list of conditions for which, in early 2020, COVID was obviously not yet on the list, so it got marked as "Spontaneous".During COVID I had what was clearly a COVID prompted single pneumothorax (collapsed lung). The standard medical advice is that there are three types of pneumothorax: puncture (e.g. from a bullet); disease-induced; and spontaneous. Once healed and after a rest period (~12 months) puncture pneumothorax is not a bar to diving, but spontaneous is a lifetime bar. Disease-induced, however, is a "depends on the disease" case (which I understand from the one useful doctor I've talked to is a function of whether the disease acts on existing weaknesses in the lung, or creates those weaknesses.
Alternatively I have a bet to see how many times I can get the word "spontaneous" into a single thread before anyone notices.
