Hello,
Sorry to say but you must be aware of the treatment to be administered in your body before starting it. It is the standard protocol to take consent for such type of procedure of giving injections in penis, without that one cannot perform it as such.
It is moral and legal responsibility of your doctor to explain you the problem, all treatment alternatives and then proceed further.
Papaverine is a vasodilator drug used to increase blood flow through smooth muscles of the penis. Side effects are allergy, local rash, itching, systemic absorption and nausea, flushed face, headache,
dizziness, allergy, weakness, stomach pain,

Side effects include penile erection longer than 4 hours, irritation in penis, urethra, difficulty or blood in urine, headache, red face with flushing, dizziness, allergy rashes, chest heaviness,
