My INTENSE / DEBILITATING Right Groin Pain resolves with rest then comes back 8 weeks later

Can a hernia pain come and go? like can the pain last 10 days and then subside for three months or for one month after extensive horizontal rest and decreasing all activity?
– Yes, it is possible.

Pain at the upper inner thigh, radiating from the groin in the front, can be from an inguinal/groin hernia.

Evaluation by your hernia surgeon is valuable regardless of its timing with your symptoms.
