Headaches after Trimix

I've gotten a ton of good info from this forum, and hope to get some feedback on a problem I think I'm having with Trimix.  I've only tried the injection twice, but from the first, I've had almost constant low grade headaches which are only eased with high dose Motrin.  I rarely had headaches prior to using the Trimix.  They seem to ease after a few days with no injections or sexual activity.  I'm not sure if it's the Trimix or the effort put into achieving climax that is the cause.  I'm using the recommended dose of .20, and so far haven't really been overjoyed with the results.  The last injection gave me about 90% right off the bat and then in about 10 min. it fizzled.  My uro said I could go up to .30, but with the headaches, I'm not sure if that would be wise.  Anyone else having a similar reaction?

If you do a search, you will find that a large number of men who use trimix have headaches and or other pain problems. Pain is very common.   It comes from ther Alprostadil component of the mix.  Alprostadil also marketed as Caverject is eliminated when you use a "bimix".  The bimix has papaverine and phentolimine usually in a 30-1 mix.  It works well for many men without the pain.  It works for me.

My doctor recommended 5MG Cialis while taking trimix. However doctor specified injections not more frequently than every other day.
