This is Dr. David
are you looking to stay with homeopathy or are you willing to try conventional therapy?
have you tried calendula cream?
you can try steroid cream for a short term basis as well.
like for 1-2 weeks to help the rash.
is the rash itchy?
sounds like a bad eczema flair up.
often times as the weather gets colder and the air gets drier, this can worsen eczema.
some patients are allergic to sulfur medications.
skin testing can confirm this
I would stop the sulpher and try an antihistamine cream like benadryl cream to help decrease the rash.
oral benadryl antihistamine might help as well.
Lithium Carb works best in case of a rough rash all over the body and tough, dry, itchy skin
In fact, in cases of eczema, even a 30 C of sulfur can cause a flare up or aggravation. This often proceeds a disappearance of the eczema, although it might take a higher potency later.
The thing to do is not repeat the sulfur and report to the homeopath. IIf needed, the current dose of sulfur 30C can be antidoted, although in most cases this is not necessary if you can live with the rash until it dissipates. However, this should be monitored by your homeopath. In the case that a new symptom picture is emerging, a different remedy would be used, thus creating a "dynamic" antidote.
Do not use anything topically as this might interrupt the treatment and prevent cure. Unless approved by your homeopath. Calendula is usually safe, but even so, it can still be a sub-optimal choice compared to follow up for the correct remedy procedure.
A sulfur 30C rememdy does not have any sulfur in it, so it would not cause an allergic reaction.
There is no molecule of sulfur at a 12C potency.
I am a classical homeopath and I would be glad to offer further suggestions.
