Hi,
Noted the history of your using friend's vaginal toy but got some problems as you have discussed well.
Since there was an
injury there is surely a chance of infection that can be develop easily.
Hence IW ould advise you the following:
Consult a Doctor for clinical examination so that exact things can be known.
Tests of blood and urine.
Appropriate antibiotic as needed.
Local application of liquid
povidone iodine can help a lot.
Take plenty of oral fluids for clear urine.
Stop worrying.
Never use such things used by others.
But yours and be assured after reading instruction on how to use and clean.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
