Hi jobo147

This is complex so any opinion should be given and taken with caution

Best to try to find one tissue that can explain all the symptoms. That is because it is much more likely that in an injury one tissue gets injured

Muscle tears can’t explain all your symptoms. (eg increased frequency to urinate). The gluteal muscles are also the some of the most robust muscles in the body and it takes extreme forces to damage them. A masseur would be unlikely to generate such forces even with the ghastly manipulation he performed.

The increased frequency to urinate, pain in the testicles and rectum are more likely to be due to involvement of the sacral nerves at the cauda equina, sacral outlet or at the sacral nerve plexus. Dramatic symptoms are much more likely neural in nature, and neural tissue is much more vulnerable than muscle. The long time to settle can also be explained by neural involvement. The burning pain in the buttocks are typical symptoms of dural pain – that is the protective tissue surrounding the sacral nerve may be involved.

Why the symptoms took two days to develop is a bit harder to explain by a direct nerve injury It may suggest that something impinged or adversely affected the tension on the nerve rather than a direct blow to the nerve.

This has gone on a long time. Neural tissue can take a long time to repair and settle down. Are the symptoms slowly improving or are they staying the same? If the symptoms are slowly improving (eg less intense, less extensive, or less easily stirred up) then this may suggest just giving it time might be fine.

Have you sought an opinion from a neurologist? I think it is worth trying to get it properly diagnosed. From a therapy point of view I would go and see a specialist manipulative physiotherapist – a therapist that has extra training in such problems. Muscle tissue therapy may give you some symptomatic relief but probably isn’t doing much.
