That is a goodly dosage of Trimix (more normal is anything from .10-.30cc). You have to hope that if it eventually does kick-in and work right that you don't poke thru a wall or something. (since you got nothing so far a 4+ hr erection seems unlikely tho).
Any idea what the strength of your Trimix formula is? Usually something like 30mg Pap 1mg Phen and 10mcg PGE-1 (or 5 mcg or 20 mcg). Those are all per ml of water.
The only thing I can think of for the two symptoms you have is some rapid flushing out of the shot which then takes hold down in the groin area (maybe still in the corpus cavernosa .. but the portion leading back in thru your crotch instead of absorbing in the main part of the Corpus C in the penis.
So something like JamesC mentioned P&P+light constriction might work for you (but maybe cut back by 1/2 on your dosage if you seriously try it since it can enhance the effect). I do the lazyman's constriction after a shot by just squeezing around the base with thumb-index finger for 2 or 3 minutes to keep the shot in the area for a little longer. Seems to work fine.
I've never had any ache ( except the Good Ache) at .20cc of what is essentially 50mcg/ml trimix. And that easily lasts for 2-3 hrs or even more.
Oh one other item -- are you standing up while trying to get the erection going? Not sitting or laying down. << Now on second thought .. maybe for you sitting or lying down will SLOW the blood speed and help keep it around. Also I remember when I did get MUSE ache ,, standing made it worse .. lying down with hips ABOVE body helped.
<edited out 2 months -- Feb 2010 is 14 months >> I did not try injections til 2 years after surgery -- but was using pump daily for all that time -- so I am certainly limber and stretched well for Trimix now.
