Yeah, there are a lot of ways to look at this obviously, and it depends on what you mean by the "matching point". If you mean the same point, and you are doing a bilateral/symetrical TCM style treatment, I would refer to Feng Mei's reply above. If, however the matching point is a point in a related meridian it could be dicussed further.
One could take more of a 5 element stance on this, and that would require looking at those relationships and acting accordingly ( I.e. if it were a deficient condition, tonifying the Mother, or sedatiing the Father... if an excess condition, sedating the Son or tonifying the Father.
One could also, especially in a acute ( excess) pain situations, take the stance mentioned above, where one would sedate the related meridian ( i.e Hnad Tai Yin- opposite Foot Tai Yin, Hand Tayin - either side Foot Tai Yang, Hand Tai yin- opp. Hand Yang Ming, Hand Ta yin, opp. Foot Jue Yin).
