You mentioned just one spot ?
Urticaria usually appears all over the place.
http://www.medicalook.com/Skin_diseases/Urticaria.htmlIt's possible it's a delayed autoimmune reaction caused by the vaccine,
especially those yeast-based ones, and finally triggered off by your stress.

http://www.ncbi.nlm.nih.gov/m/pubmed/9892973If it's mild and not very itchy, you can leave it alone, since it would probably
improve or disappear with time, and you are afraid of steroids.
Otherwise, try applying a relatively safe and low-medium potency second-
generation steroid cream like mometasone (Elomet), which has little systemic
absorption, not to worry.
I have a tube of generic mometasone (Vizomet) in my office. You can
even apply it on your face or on babies with nappy rash.
Another second-generation steroid cream is fluticasone (Cutivate) by Glaxo,
but quite expensive. Doesn't seem to be any generics locally.
Safety of fluticasone propionate cream 0.05% for the treatment of severe
and extensive atopic dermatitis in children as young as 3 months.
http://www.ncbi.nlm.nih.gov/pubmed/11862174Two other low to low-medium potency steroid creams which are also quite safe are :
Clobetasone (Eumovate, generic U-Closone, make sure you don't confuse it
with clobetasol, which is Dermovate, the strongest steroid cream).
Clobetasone was actually developed by Glaxo in the 70s, but quite ahead of its
time, in that it had very low systemic absorption, far lower than betamethasone
or triamcinolone.
Hydrocortisone aceponate (Efficort, by the French firm Galderma).
Dr Ting used to give me this for eczema near the genital area.
Take an antihistamine like:
Loratidine (Claritine, generic Ezede)
Desloratidine (Aerius)
Cetirizine (Zyrtec, many generics)
Levocetirizine (Xyzal)
Fexofenadine (Telfast)
