Carol, To make a complete symptom for repertorization you need Location, Sensation and Modalities.
If you take the example already given you have:
Location: Feet
Sensation: Numbness, deadness, sensation of
Modality: Agg by External pressure.

Using the BB repertory, Location is self-explanatory, you'll find Sensations in the Chapter called Sensations and Complaints in General. And Modalities are found in the Chapter Conditions In General beginning with Time aggravations leading on to Conditions of Aggravation and Amelioration in General.

The BB repertory is kind of halfway between Boenninghausen and Kent - in arrangement - not in content. So you have more localizations and 'particular' rubrics than in the TPB and Agg and Amel rubrics and cross references at the end of each chapter. The strength of Boenninghausen, as I see it, is the way he found the striking quality, that is, the genus of each remedy from a mass of proving symptoms and generalized those symptoms and graded them accordingly. This means you can use a bigger more general rubric, like Agg by External pressure in the Sensations and Complaints in General Chapter with confidence that it will lead you to a promising source in the Materia Medica. By comparison the localized particular rubric found in Lower Extremities Chapter has Phos only in the lowest grade.

When you run these 3 rubrics together you get:
Lycopodium 4,2,4
Baryta carb 2,3,4
Silicea 4,1,4
Calc carb 2,3,2
Pulsatilla 4,2,1
Aconite 2,3,2
Hepar sulph 1,1,4
Rhus tox 2,3,1
Phosph 2,2,2

This result gives you a place to START accessing possible remedies which will suit the case. All of these remedies have numbness of feet, and in their own way are Agg external pressure, and I dare say a great number of people enjoy chocolate and ice-cream too, so... if we can all put our over-reaction on hold for a couple of minutes, we can see that we have quite a few possibilities to work with.

Namely, concomitants, for instance, if the case was taken at all, at first and in an orderly fashion, you might recognize Symptom number 1361 in the Lycopodium proving that would give a highly characteristic feature to the case. But no case has actually been taken yet so you have possibly missed out on the most suitable similie by surging ahead with half the story...
Similarly, you might find it interesting that Silicea has a record of healing traumatic injuries to the spine and that fact may become relevant to the case...
Phosphorus is definitely a contender, but without having taken an actual case, (hoping 'over-reaction' button is still on pause) be careful if you build a case around non-morbid 'constitutional' symptoms that are not characteristic to the case. Everyone I spoke to last week really, really loved chocolate, funnily, not so this week. Be careful, about which indications you are using to "confirm" a case, it is possible to build up a case around these types of things and make it sound convincing, give the remedy and put a good spin on the result, but I would say, stick to the facts of the case, and that means take a proper case *first*.
