Hi Jonathan
I cannot tell you whether you will be successful because that's down to the DWP, but certainly, there are a lot of people with arthritis who have made successful PIP claims.
Take a look at our pip guide to see if you wish to put in a claim and try not to be overwhelmed by the size of the guide. The advice contained in there will give you the best possible chance of making a successful claim if you want to.
I can't say exactly how long the process will be because times are varying across the country but it is likely to run over several months.
