Meg, you need more symptoms and modalities. For sure Rhus Tox is the first to think but also Na-Sulf, Dulcamara... but also other remedies.

So tell us more about modalities, localisations, wandering ? pains, reaction of tissues and surroundings.
I think that your Murphey is a really good repertory. Kent is good for beginning and also basic but take the case... this is important.
