Dear Nic
Sweating is actually a good thing.
People that do not sweat should worry.
smelly /stinky sweating is subjective-everyone has their own version of what 'smells'.
so my reply is general and not specific to you or your case: you need to ask your "own" homeopath regards "your" specifics.If you have done this already -may I ask what your homeopath has come up with?

So
In "general" your skin is an ellimination organ,thus what is within gets expelled out via one of your ellimination organs.
1-If there is a smell it may be due to internal toxins being expelled.
2- It may be strong spices you have ingested being expelled (garlic will do this).
3-Various patient-Miasmatic predispositions have certain smells (more on this search miasmatic casetaking in homeopathy).
