My nephew has a big robin egg bump on his forehead that has been growing steadily for about 8 months and also seems to have cognitive issues that have gone undiagnosed. His mother won t take him to the doctor (he is 22 now), but I m concerned. He has extreme social anxiety (not related) and is slow cognitively (speech is slow and difficult at times and he is almost catatonic at moments) but this bump appearing is a new thing so I m wondering if it could be connected. Sadly at his age it is difficult to get him to a doctor without his compliance but if I have some sense of anything this may sound like it may help me to advise him.
