Hello
Rash on the upper part of body as well as lower part .
Prednisolone is not working .
This rash may be due to these reasons:
1 Urticaria , due to antigen antibody reaction and cause is not known . However allergy skin test find out the reason but this is a long procedure ,so this time not fit for you .
When such patient visit I prescribe montelukast=
fexofenadine one tablet in the night till complete cure .If no response within 5-7 day then
consult a dermatologist and get his opinion.
2 Worm infestation , diagnosis can be confirmed by stool examination .
3
Dermatitis , diagnosis can be confirmed by physical examination by a dermatologist .
In my opinion this rashes is not due to tension ( after the death of you husband , sorry for that loss ).
However , this may be scabies .
So in my opinion consult a dermatologist and get his opinion.
There is no
home remedies for such rashes .
Good luck.
