It was an MRI Brain Scan. Medicines are only one bisoprolol 2.5 mg tablet and 2 x150 mg dabigatran etexilate capsules daily following his aortic valve replacement. He does not suddenly lose balance - he is off balance all the time and needs to lean on something for support if he wants to stay still. he cannot write his signature any more as he cannot keep his fingers/hands under control. His blood pressure has been checked very recently and is normal. He does have a slight mis-beat now and then which apparently is also normal following this sort of operation and his blood pressure is monitored regularly.
Sorry, realised that I had not mentioned that my husband is not in any pain which I hope would remove the possibility of cancer? Regards digestion he does take quite a long time to eat these days but he does eat sufficiently well. His weight has now stabilised.
