Hi MJ.
First, if you're only 3 1/2 months out, and you've been doing that level of activity for 2 months, that seems very early for that much activity. In my original post, I was 10 months post-op. My issue was strictly related to running. I would get sore around 3/4 to 1 mile into a run. If I stopped I was fine. If I tried to "power through", the soreness could last 3-4 days. To be honest, this has never fully resolved. Dr. Gross says that ends up being the case in maybe 10% of his surgeries, and he does not know why.
So, for about 7 years I hadn't run. I could do an hour of HIIT training. I ccould run the bleachers until I couldn't. I could/can do boot-camp style workouts, including things like box jumps - with no pain - but I couldn't run for more than a mile without this ache setting in.
About 18 months ago, I started going to a boot-camp type gym. In it, I did more lower-body stuff than I've EVER done in my life. After about 4 months of this - when the weather permitted - our group would go out and run a mile after class. I was able to do that without the telltale pain. Another day I tried a run, and was able to go 2 1/2 miles before the pain settled in. So, I believe what I'm figuring out is that my issue was always that I probably had under-developed lower-body musculature. Prior to surgery, I ran and biked, but didn't really do much lower body strengthening.
Unfortunately, shortly after this realization, hip #2 started to go and my boot camp and running came to an end. Because of COVID, I had to wait 5 months to get my other hip done, so I am now 4 months post-op on hip #2.
I'm not a doctor, but I would say that you were probably overdoing it for such a recent surgery. The last thing you want is a femoral neck fracture because you're pushing it too much, too soon. Just dial it back for a few weeks, then work back up slowly. You've probably read this before, but the recovery is a marathon, NOT a sprint.
Best of luck.
