Your previous post is on the following link
www.benefitsandwork.co.uk/forum?view=top...=10&id=102491#127222 Our advice has not changed from the last time you posted
It's entirely up to you whether you contact the DWP or not.
The ESA50 is you opportunity to explain your limitations in your own words without constraint, if you do not complete one then the Decision Maker can only make a Decision on the information provided by people who at best may only know your problems from a distance and at worst are evaluating you over a one hour interview, never having seen you before.
I'm not sure what you mean by
Am I likely to be called for assessment without a medical?
The ESA assessment is not a medical assessment of your conditions but rather a functional assessment of your capabilities in relation to the ESA Descriptors, a very different thing.
