Hi, my name is summer2015!

Hi I have had to give my job up due to the fact that standing for long periods of time on my legs is very painful I do one shift and I can't physically stand properly for two or three days afterwards I don't have the qualifications to do a job that entail sitting down and at the same point my legs then do still seem to swell around the ankles and everywhere because my legs are hanging over a chair could anybody advise if I would be entitled to Pip or any other benefit because technically I would not be fit for work I'm 56 years old thank you
