Oxygen Levels

This happened to my husband, but he was already in hospital at the time. You need to contact your specialist nurse as you need your oxygen level above 90 at least. You may also have a low blood count. Make sure you take some deep breaths, in through the nose and out through the mouth, then check your levels again.  Definitely don’t wait until January. 

Thanks for your reply, however I do not have a specialist nurse or contact with a consultant.

There could be 100 different reasons for this, 99% of them nothing to do with PCa.

I assume your 'next injection' is HT, which would certainly explain the fatigue (that's the 1%!). But not necessarily the oxygen drop.

But any breathing problem should be checked out. Contact your GP.

Go to your GP as soon as you can this needs to be checked out.
