PIP Eligibility Criterea

I am currently working, but have had lots of absences due to what has finally been diagnosed as CH. I have just come out of a level 9 attack that kept me off work for 2 weeks before subsiding to levels 5-7  (occasionally level8) and I have been back at work trying to work through it.

I'm really struggling now and an option of reduced hours is on the table. However as a single income household, theres no way that I can do this without additional financial support. I think the CH is episodic and without the medication, I would spend most days at level 8. Looking back over the last couple of years I'm sure that I have relatively pain-free periods lasting a month or so.

My question is, can I qualify for PIP even though I'm currently managing to get up and dressed and out of the door 5 days a week, and have no help or support.

Thank you.
