This Is With Regards To My Husband. He Has Been

This is with regards to my husband. He has been afflicted with several symptoms over the last 3 years. In 2013, he was diagnosed with a heart valve backflow - the specialist has advised surgery within the next 5 years. In the same year, he was also diagnosed with an enlarged prostate for which he has been taking medication. The problem worsened early this year - he is unable to sit for long periods of time and has to use the washroom many times a day to urinate and is now self-catheterizing. He will be having surgery within the next 4 months. He also had a brain bleed in June - some doctors are calling it a mini-stroke. It has left him with partial numbness in his left arm and leg. In addition to this, his hemo count keeps dropping, he has lost 40 lbs over the last 6 months, is constantly feeling tired, is unable to get a good night's rest, and had a thyroid biopsy 2 weeks ago. We are still awaiting the results. He has been sent to numerous specialists, taken many tests and done bloodwork several times. No one has been able to say what has caused all these recent problems. Our frustration level is growing - who can tell us what is causing all of this? If you can help us out, it would be most appreciated. Thank-you.
