@Cataceous, that may be it. Do you know what the long term concerns are? Is it
this?
Virtually all injections trigger headaches for me, and one theory is that it could be related to the oil (inflammatory response of some sort). As I have posted before, this has led me to use Natesto for much of the last few years. I just recently decided to give Jatenzo a try. While a pill twice a day is less convenient than periodic injections, it should be easier than a nasal application three times a day.
If Jatenzo does not work out, my next step is to try injections one more time, this time with the low viscosity oil, just to see if it is better tolerated than the others. If neither of these are tolerable, than it's back to Natesto....
