The severe pain and aching, requiring motrin and warm baths are not normal at all. For the vast majority, the worse is a slight ache from one of the compnents of the trimix, but seldom described to that pain level you describe.
Now, then, how about
you describe your injections procedure in detail, listing every steps, no matter how minor, that you take for the injection? Needle gauge, length, insulin syringe or other? Include the
location of the stick, the angle, if any, the length of the needle, even the thickness of your penis during the process. There's something going on that isn't 'normal' and the best place to start is to look at every detail of you method of injecting. Do you experience any swelling spots or enlargements in just one area of the penis.
I keep asking questions to try to help, but you need to answer all my questions, so I can help you the most by having the most information you can provide.
