Unfortunately an occasional side effect of massage is that you can occasionally feel a little nauseous after the massage. Whilst you will hopefully feel relaxed, looser with less muscle and joint pain, it is possible that you may just feel a little off colour for a while.
For most people, this side effect of massage only last for a relatively short period. Some people will need to have a lie down and sleep. Others will drink plenty of water to feel as though they are giving their system a flush. Regardless, in the vast majority of cases, the nausea is only a transient hindrance.
There is much discussion regarding the cause of the nausea and dizziness after a massage and it may well be the case that there are a number of different causes. One theory which is discounted by most therapists is that the nausea is caused by toxins that are release by the massage. For a discussion of this fallacy then please check out www.innerwestmassage.com.au/massage-toxins.php.
A recent hypothesis is that “Post Massage Soreness and Malaise” is the result of a mild case of Rhabdomyolysis which occurs when muscle cells are damaged and it interferes with the blood chemistry.
Personally whilst there may be some evidence to support this theory, if you follow this theory then you would agree that the deeper the massage, then the more likely you would be affected. Although this is a personal viewpoint, it doesn’t tally with my experiences.
For me nausea is more likely if I haven’t had a massage for a while and I have never noticed any correlation between the pressure/intensity of the massage and the degree of nausea experienced. I tend to subscribe to the theory of Dr Keith Eric Grant who considers that massage is about returning the body towards homeostasis and that the nausea may be the result of giving the lymphatic system a bit of a kick-along. Other therapists may argue differently to this but regardless this type of nausea post massage is very normal and not a cause for concern.
However, if you start vomiting and feel extremely dizzy post massage then that is a different kettle of fish. This happen whilst I was massaging someone a while ago and we had to stop the massage after about 20 minutes as the client was unable to continue. Although massage had only been carried out to the back, just the act of lying prone was too much for the client. Although she recovered and started to feel better once she rose from the table, this was not a normal state of affairs and seeing her doctor was the next step.
Although uncommon, one possible explanation for the extreme nausea in this case is atlantoaxial instability.
Atlantoaxial instability can be considered as a loose upper spine and is the loss of the integrity of the joint between the top two vertebrae, the atlas and the axis. For some people who may have had a neck injury or trauma, then when they move their head or neck then a bone projection (the “dens”) from the axis may effectively make contact with their brain stem. The result of this can range from mildly unpleasant through to downright dangerous.
Although there may not have been a formal diagnosis of the condition then a massage therapist should be alert to the possibility. A client may be particularly tight high in the neck or be very guarded and protective of the way they hold their head. If any alarm bells are rung for the therapist then they back off with the intensity of their work and use the adage “too little is better than too much”.
