Hi marvelwoman1uk
We can never say that someone will definitely qualify for PIP, but it sounds as if you should with such restricted mobility. You can ring the DWP and put in for a change of circumstances and they will send out a review form. Make sure that you read through the PIP Guide to PIP Claims and Reviews - so you understand the process and give a full picture of your mobility issues. Don't assume they even know what lymphedema is!
