Dermatology Questions? Ask an Online Dermatologist.
Where is the rash located? Does it bother you in any way? Itching? Burning? Can you attach an image? Has anything been tried on it? etc?
I would say that for now a different cause isn't of concern. This is still in the ballpark of stress reaction. Even if it began at a time of lower stress, you may have unconsciously been aware that the stress was about to ramp up.
I would advise careful attention to exercise, a minimal of 30-60 minutes of brisk walking daily. And avoiding alcohol and drugs. Trying to eat right and spending time in contact with supportive people.
It may be something dietary as well. Sometimes a dietary cause can come out at times of weakness. So perhaps a food diary to see if there are certain foods that are associated with worse symptoms at day.
If regular medical care isn't helping, alternative providers may be helpful.
Any other questions?
Sometimes Western medicine doesn't have good enough answers. For some people seeing a Chinese medicine specialist or a naturopath can be more helpful. Sometimes allopathic (Western) doctors try their best, run tests and can't come up with answers. In that case it can be helpful to switch to a different "paradigm". I hope that's not confusing. Mostly Western (regular) medicine doesn't have all the answers sometimes and using a system that thinks differently about the problems can help.
