It sounds as though the liquid paraffin was a bit too much for her, eating substrate is rare, a blockage could be caused by a number of things & the vet would need to investigate that further really.
Is she still the same now, better or worse?
I would start her on probiotics asap, make sure she stays well hydrated if you can & either go back to the vet or find another who may have a bit more experience with hams.
Hope she does get over this.
