Damp spots, wall already injection treated for rising damp

Hello,
Searching through the old posts, this subject has already been discussed to death :<)
My problem is slightly different. One of my outside walls which abuts on my neighbour's garden, has traces of mold and which has caused the paint to blister. The wall was injection treated for rising damp about eight years ago, and the wall itself was plastered on the inside and painted about four years ago.
I checked the ouside of the wall in my neighbour's garden and there are no piled-up mounds of earth that might have caused moisture to bridge across the damp treatment. But I noticed that the wall is not platered on the outside, and some of the bricks in the wall are damaged. Is there a treatment that I can use? Is inside or outside treatment the best? For now, I used a coat of varnish on the inside wall and then repainted.

The only effective treatment for damp is to find the cause and repair it. Injecting things into brickwork is rarely effective

All that will do is trap the moisture in the wall (assuming the wall is actually damp and you don't just have condensation) and cause the coating the fail again.
You need to find out, or work out, why the interior wall is damp not just splash waterproof coatings about willy nilly.
All the normal questions:
What is the walls construction? Are there anly leaky gutters or down spouts that wet the exterior of the wall? Is the room heated? Is the room ventilated? Have the windows being changed from single glazed normal casement to double glazing? Is the room used for drying things? clothes, etc Is the room close to a kitchen, bath or shower room? Has there been any furniture close to the bit of wall with mold?
