I think the first month is difficult for a lot of reasons. Physically, it takes awhile to get used to have something in your body. Little aches and pains, soreness. Regardless, you've had an operation before which you were likely tired. So, your body will still be recovering from the fatigue created by both the condition and the operation. Emotionally, I was very concerned about every physical feeling; was it normal? was it a problem? I was anxious about the restrictions. What would happen if I accidently did x, y, or z. Finally, while I wasn't aware of it at the time, the FACT that I HAD to have a pm implant took some time to accept. I am 3 months in now. I am back at the gym doing mild workouts and walking at home. I now understand the adjustment more as a process, likely quite varied among people. I can physically do more now with less effort; I am less fatigued; I don't worry as much about little small feelings of discomfort (still very careful about what, and how much, I do). Over the next months I anticipate 'moving along' to the next level. From what I have read, in the first three months the device 'settles' and is finally solid by a year. Medtronics (my pc maker) has a wonderful website and call centre with nice people and helpful material for reading. Look for a patient website by your pm maker if it isn't Medtronics. They will likely have one. Finally, know that you are not alone in this. People with pms are young, middle-aged and old, and do share their experience. Finally, check in periodically with your doctor or device clinic and ask about the things that concern you.
