Scheriproct is good, I think it has some kind of anesthetising thing in it which helps a lot!
Have you had them graded (into Stages) and been given any options as regards having them sorted? Mine were found on an endoscopy and sorted by the surgeon who did it and the sorting bit was over pretty quickly, a bit uncomfortable but not too bad (and that's probably partly to do with having the camera up without sedation beforehand).
It's not a pleasant thing to have, I found that those moist flushable toilet wipes were quite soothing for external irritation and gentler to clean with.
If you have any issues which maybe antagonising them or making them worse, you could look into that e.g. straining through constipation as a GP may be able to help with that.
