Hi rag33,
I am not a runner, but I am a professional skier and windsurfer, as well as an enthusiastic tennis player and surfer. I will share some observations from my experience with one resurfacing that is almost 11 years old, and another that is about 10 months old.
*You are only about 3 months into a soft tissue healing cycle that takes 18 months to be mostly complete. No matter how athletic we are, my understanding is that it takes that long for the body to completely heal and remodel the soft tissue.
*As my doctor says, you can expect lots of twinges and little pains over the first year.
*Some doctors, like my surgeon Dr Gross, do not allow any running for six months, so 3 months is a little aggressive in the eyes of some surgeons.
*Dr Gross does not allow any sports until six months. When I started back to skiing at six months, I experienced lots of little aches and pains everywhere around my hip at various times. When I called the office, they were reassuring and suggested taking NSAIDs. It always got better within a few days.
*At 10 months, I am skiing every day, but if I push too hard I can still make the newer hip a little sore. Last time it was 18 to 24 months before that completely stopped happening.
*After my first hip, I got back into tennis at one year. This caused some pains which again lasted until about 18 months, and then went away completely.
*If something concerns you, it is always best to touch base with your surgeon, even if it is just for piece of mind.
No one on this site can, or should, give you medical advice, but perhaps some of my above experiences might give you some insights.
