About 2 months ago, I got pain in my groin (inside and now in front). I saw an orthopedic doctor who did an xray and MRI. He said 'you have arthritis and need to see an orthopedic surgeon'. He did ask if the pain went down as far as my knee. I said no...however a day later the aching goes from the top of my groin to my ankle. Occasionally I get pain in the hip. Most bothersome is the aching in the thigh and down the leg and groin pain. 1. why did he ask if pain went down to the knee? I've called to ask. No reply yet. 2. He didn't say what kind of arthritis. Does it matter? 3. Yes I'm hitting 70 and do have arthritis but how do I know that is the cause? (I'm picking up a cd of the MRI and report next week) 4. I'm more than concerned as I'm allergic to most all antibiotics so infection being possible with any surgery is scary for me. The center I'm going to doesn't have an infection disease control dept. 5. Am also wondering how well Tens etc. does for this major surgery as opioids cause severe constipation for me. I certainly won't be using much of these. I appreciate any comments. I realize it's early in the game, but I wish I had looked on forums before my last surgical escapade. They got inconclusive biopsies, pet scan of 6 out of 10, so ASSUMED it was lymphoma in my sacrum...took the bone out with the tumor which has put me in chronic pain for life...found out it was Castlemans and I didn't need to lose the bone!! That was after 3 famous hospital/doc visits. So I trust forums now more than doctors. Too bad you all can't do the surgery for me! Thank you.
