A wound like that needs to be checked by a vet to be certain it isn't infected and to see if it is something that needs medication. Sometimes surgery is necessary, but if you have it looked at early, treatment could be much easier and less expensive. Please have a vet look at it to assess the lump.
Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
