Not sure where I stand?

Hi guys, just joined here as I am at my wits end and was wonder if anyone could give me some support.... I had a craniotomy 4 weeks today after they found a lesion on my left temporal bone (long story) now after surgery the neurosurgeon said that the operation went well but they tore the dura as the lesion that’s attached to the bone itself was very sticky so when they lifted the bone up it ripped which was fine they put in some fell stuff apparently to stop the car fluid leaking... so they also used a titanium mesh to replace where my bone is missing... so to cut a long story short.... I still don’t have any results, I phones the secretary of my neurosurgeon and she says still nothing so I am beginning to worry .... my middle son also was diagnosed with a BT in 2011 aged 7 and his results where back in 7 days so why does bone one take so long any ideas???
