Getting ready for DH surgery

I was hoping to have a calm fall but it looks like those hopes are dashed. DH went to see the orthopedic dr yesterday and he spent about 30 minutes with us going over his films and MRI results. He has 2 tears in the rotator cuff and the dr explained that it will not get better on it's own. He showed us the arthritis in his neck joints and explained that they could not know if the worst pain was coming from that or the tears. However, he guaranteed if this was let go, it would get worse. If after fixing things the pain is still in his neck that can be addressed but he felt dealing with that is usually more complex and this might alleviate the problem and he would not need anything for the neck.
We now have 3 weeks to get the clearance from his primary physician, his cardiologist and his pulmonay dr. I scheduled those appointments right after we left and we will have 2-3 dr appts each week. In addition, he has an appt with the oncologist, the urologist and the gastrologist! Like I said it is going to be busy going to see docs!
I am not looking forward to him having this surgery. I know it is extremely painful and will entail a lot of therapy but if it gets rid of the pain, it will be worth it. My brother just had surgery about 8 weeks ago and he is still not back to where he had hoped to be by now and he is almost 25 year younger than DH.
I just started The Dukan Diet which was ordered by my dr. I had a fasting blood sugar of 125 at my last visit and she told me that this might keep me from developing type 2 diabetes and bring my triglycerides back down so I am willing to try it. However, it is very restrictive-I am in day 4 and so far I am staying with the plan but it is not easy. I have developed a perpetual headache which I think is from the withdrawal of sugar from my system. For 10 days I am on a protein diet to purge the system before adding back vegetables and they are limited.
Keep us in your prayers that we can deal with these health issues.
