I had a total anterior hip replacement in April. The surgery went excellent and I was back home in 2 days. At my first and second post op appointments, everything looked fine and healing nice. In August I started walking longer distances and was walking 2-3 miles a day and some days 4 miles. During the first 30 days of walking I had no pain. Then last Friday I got a pain in my thigh while walking. I stopped my activity and went home. The next day I just walked around the house and had no pain. Then on Sunday I walked about a mile with no pain. Then on Monday I had a very sharp pain while walking at home so I called my surgeon and he had me come in for a checkup and x-rays. The x-rays didn't show any issues with the hip replacement. He thinks my pain could be nerve related so he sent me home with Gabapentin. The pain is sporadic, and only lasts for approximately 5 seconds but hurts like h..l. I don't know if anyone has had this issue but I'm very frustrated as we still don't know what is causing the pain. I told the doctor I wanted a CT Scan and he agreed so next Saturday I'll get it. For now I'm back to my walker and not placing any pressure on my leg. I thought it could be a muscle strain but the weird thing is that the pain is off and on.
