Thanks for the query,
Stress related bumps are mainly related to herpes.
However these lesions are associated with other symptoms,
Mainly itch is present.
may be seen in conditions like as epidermolysis bullosa acquisita
A biopsy would be needed to confirm it.
You can use a mild oral steroid paste like fluticasone
This will give you relief.
Please meet a dermatologist
for exact diagnosis.
