General metaphysical principles behind skin rashes

[unity100]

Has anyone heard of any metaphysical explanations for such rashes?

I encountered such a situation before, not for me but someone close.

The situation manifested itself during times of considerable stress/pressure due to whatever reason (academic, family, other), and it exacerbated on days of exposure to the sun, especially in summer.

Talking about any spiritual reason (not metaphysical mechanics) in regard to the person who is encountering these would be very difficult since such manifestations may be tied to deep psychological, spiritual or subconscious conditions, or even pre-incarnational arrangements or even things relevant to past lives. Like how the famous flower allergy example which is often quoted exemplifies.

Best would be to be observant of the conditions immediately before, during or after the manifestation or surge of this situation and try to track it down.
