Good day Lynn
Sorry to hear your news about your other half.
I to was diagnosed with MM at 67 with all relevant bone lesions. There are others on this forum who can help you with what all the relevant test results mean, I personally do not take much of that in but my consultant is excellent and he tells me if all results are going in the “right direction”.
Pills and injections are, sorry to say, a necesary part of treatment to help him carry on with a near normal life as possible. You haven’t said if he is in pain or restricted in anyway.
When I was in remission I travelled to Australia and there are others on this excellent forum who still travel and can offer advice on travel insurance etc.
Hope this helps and that you can both move forward albeit with possible limitations.
Regards
Graeme
