Damp Proofing

Slight rising damp on party wall - is it worth

We've recently had our kitchen renovated, and we knew about a small issue with damp on the right hand side party wall. I noticed a small amount of salts coming through the wall (and some paint bubbling), but this was when we had a small backroom (which wasn't heated or well ventilated). Now that we've opened up the entire kitchen, and added a radiator on that wall, the problem has greatly reduced - However, this morning I noticed, some dusty paint/salt as well as a small bubble of air under the paint. It's a small patch (no bigger than an A4 sheet of paper), so I'm hoping it might naturally dry out. From reading, it would appear that the radiator (and ventilation haven't fully dried out the wall) so we might have to investigate DPC chemical injection, so my first question. 1) Can the chemical injection be done if there is NO access to the external wall (as it's the party wall). 2) Is my neighbour also liable? And will they benefit if I carry out the DPC (on the party wall). If not, do I need to notify them if I'm carrying out the work? 3) Will tradesmen do just ONE wall? thanks in advance.
