I am in my 70's but slim and walk at least 5 days a week for about 30-45 minutes with my dog at a good pace.
Several weeks ago I suddenly had the sharpest pain in my upper right leg area and close to the groin. For a few minutes I didn't think I could walk but was able to and it gradually became better. However since then every now and then same thing happens without the excruciating pain but still painful. I also find that if I press into the area of my upper leg near the groin as I walk it seems to help. I am still able to go on long walks as it seems to stop hurting after a while.
I am concerned about this though as it still doesn't feel right. I could go to a specialist but prefer to avoid them unless absolutely necessary. I am in the process of trying to find a good chiro in my area of Maryland. In the meantime do you have any idea what might be causing the pain?
It's good to hear of someone of your age who is so active; congratulations.
The first thing to rule out with pain in the upper leg and groin is hip arthritis, but this is unlikely because of the sudden onset; degenerative changes are characterised bygradually increasing stiffness and then pain.
Lying on your back, pull your knee to your chest, and then towards the opposite shoulder. Then do Patrick's Faber test, as in the graphic. Compare with the other leg. If these provoke pain and stiffness in the groin then you should have an xray of the pelvis.
An inguinal hernia is a possibility. Your medical doctor will examine and advise.
Most likely is muscular or ligament condition in the groin. Several large muscles pass through the area. Sitting in a normal chair, using a little oil run your finger from the crest of the hip through the groin to the inner thigh. Is it very tender? See a local chiropractor.
I hope this contributes; let me know what happens. Meantime start gently exercising your hip by pulling the knee to the chest every morning, and then rotating the joint.
