Dear Silver listers

I have been requested by a desperate friend of mine, to ask the experts about a 
problem he has, and if Silver will work, how much and how to take it.

His symtoms are:
One swollen gland or lump behind his right ear (in line with the ear lobe)
A few swollen glands or bumps under the chin (none anywhere else in the body) 
This seems to confuse the doctors.
None of the glands are painful in any way - not even if pressed quite hard.
A skin rash that starts with dry skin, and end up with small red marks on the 
face.
Although his temerature never goes above 36.5 celcius, he says it feels to him 
like his skin on his face is quite warm.

Does anyone have any ideas? He has been using a cortisone cream for a while now 
- but the skin seems to loose elasticity from this.

Any help would save him a lot more mental anguish

Many thanks
