Newby with stupid questions

Having struggled to sign up here because my brain isn't functioning as it used to, and my vision is blurred and I've lost my sense of taste and it may be all down to the steroids or not. I am feeling really annoyed with myself.

I had several, what were thought to be strokes starting 5 weeks ago, I'm now told that I have a lesion in some sensory part of my brain, but quite what it is no-one is prepared to commit themselves. I've had a Cat or two, and MRI and I have a Pet next week. Whether it's primary or secondary is an open question. One surgeon doesn't want to do a biopsy but another wants to reconsider.

I suspect that the dexamethasone is causing the side effects, as I've said, blurred vision, loss of taste, burning sensation to the tongue, sleeplessness, raging hunger- if that is the case then I can get on with life. If the symptoms are from the tumour then I ought to be a bit careful because it's boring trying to get an ambulance when I suddenly can't breathe.

I'm old, depressed and with an awful lot of things to do to keep going, or to start packing up years of accumulation so that my poor wife doesn't have to sort everything out.
