PIP Assessment 30th Nov

I am having my PIP assessment on 30th Nov 17, 9am being changed from DLA, They also moved me previously to ESA + support from Incapacity benefit, what's the wait time for results as already stopped this months DLA.
Been to 2 hospitals within a month, had biopsy and have told me I cannot have a replacement R/knee,for previous knee replacement even though there's movement in the in it, then today been told by a spinal consultant that can not have op on my spine for extreme pain, just have to manage without pain killers because of multiple allergies to medications etc. I have other medical problems T2 Diabetes, Chronic Asthma, severe walking problems with R/knee will they add this to assessment info!
