No STD can pass through intact latex or polyurethane, so you did not get an STD if the condom was in place before there was any contact. Urethral discomfort without discharge is not a common STD symptom anyway, and the other symptoms (body weakness, leg discomfort, etc) are not those of any STD.
Highly concentrated urine, which can result from dehydration, might cause minor discomfort when urinating. (If you are so compulsively focused on a computer game that you neglect fluid intake or eating, sounds to me like you need counseling about that addiction!)
See a provider if your symptoms persist, but you can be sure you don't have an STD, at least not one you caught during your exposure last Tuesday.

Thanks for a prompt reply. It is comforting.
What worried me was areas not covered by the condom ...
