Testicular “Lumps” worried

Hello and thank you for reading hopefully someone can relate. My husband found 4 lumps in his scrotum last Thursday 3 are not attached to anything and 2 have since disappeared so 2 are left.

our worry is that one IS attached to his left testical but only semi attached if that makes sense? It's about the size of a pea you can hold it in your fingers but it's not completely free it's like half on half off ? 
we saw the GP yesterday and have an urgent referral but the wait is torture.

i wonder if anyone has had a similar semi attached lump ? 
many thanks x
