Congratulations on your new BHR. Most people have problems with the meds. Many take stool softners.
The normal precautions are to take it easy and listen to your body. It is best not to cross your legs and if you sleep on your side - put a little pillow between your legs. A lot depends on the surgical approach that is used. If you just be cautious and don't do a lot of bending, sititng on the floor, crossing your legs etc., you should be OK. He might have precautions listed on his website. The large ball components of the BHR do mean that it is almost difficult to dislocate it after you have healed. Most surgeons want you to be careful for about 6 weeks. The muscles and tissue around the hip are very weak - so it is best to best to be cautious. Some people drive quickly if they have an automatic car and have their left leg done. Then no many problems with the right leg. If you had your right done - you need to wait until you can lift your foot quickly to go from the brake to the gas pedal.
It takes about 6 months to heal to the point of doing most normal activities, but a full year for a complete heal. Most don't want you to run until about a year out.
Don't push too much early. If you push, you will end up with swelling and need to ice, raise your leg and take it easy. If you are using one crutch, don't stop until you don't limp. That was my advice from Dr. De Smet. I used one crutch on the opposite side of the operated leg for about 3 weeks.
So much is common sense and taking it easy for a few weeks. Walking is good, but remember that you have to walk back for the trip. People get out and keep walking, then realize they don't have the energy to get back!
