It may be, or it may be some other reaction.

What is on the other side of the wall, and what is the wall construction?
When did this first appear?
Does its appearance coincide with any rain?
What is the room used for?

Is this blistering some sort of damp ?

It is appearing on an internal wall - what is it and what can I do to sort
it out.

Any help / advice would be appreciated

Thanks
