i have waited for nearly 6 months for a o2 assessment because my oxygen level is really low down to 83 at times. but i had a chest infection and now because of that i have to wait for six weeks before i can have one. a new appointment came and its October for my next one ! it is really affecting me when i try to walk as my legs ache like mad. I am wondering if they are trying to cut down on oxygen I am sure i have read it somewhere.
