Get pain in groin area whilst in bed, must then only lay on

Thank you for the clarification. I will be glad to provide additional information.

The other expert is correct that the most common cause of groin pain would be either a hip problem or a hernia.

It is actually more common that groin pain that is positional in nature would be a musculoskeletal problem, and the exacerbation at night is common for an inflammatory condition. Musculoskeletal inflammation will frequently get worse at night, regardless of location. And geting out of bed will frequently ease symptoms assoiated with that nocturnal exacerbation.

There are some other forms of musculoskeletal pain that can present as groin pain. There are several muscles that insert in the tissue deep to the groin, including muscles from above and below the groin. For example, a "pulled groin" is actually a muscle strain of one of these muscles. It is also possible that there can be an inflammation of the tendons of one of these muscles (tendinitis).

If you feel certain that it is not musculoskeletal, then the other expert is correct that there are only a limited number of organs in the groin, and the tube that carries the sperm is the only organ in the groin, which is why he raised the possiblity of an infection of the tube (an epididymitis). It is possible that problems affecting organs that are low in the abdomen can cause pain that is referred to the groin, such as a kidney infection or kidney stones, but these types of problems are usually not positional in nature.

Ultimately, the best that can be done over the internet is to discuss the most common cause of symptoms and to suggest over the counter options to try to relieve the symptoms. In this case, it would be appropriate to use an over the counter anti-inflammatory medicine, such as ibuprofen or naproxen. If an anti-inflammatory medicine relieves the symptoms, it does not prove the location of the problem, but there also is no need to pursue further evaluation if the symptom is relieved. If the symptom persists, it would require a proper examination and possibly further evaluation to determine the exact cause of the symptom.

If you have any further questions, please let me know.
