Yucko hun. I got the same at 20 weeks, grape size too, so not nice.

I got a cream script (cortosoidal I think) from the Drs but luckily for me, it started going down on its own so I didn't use it.

Try to keep it clean if you can. I tried to stay as regular and soft as possible to stop it being aggravated, using dried figs, prunes and psyllium husks on my cereal. Worked a treat.

Good luck! xx
