Another possible aid is antihistamine pills.  But maybe the doctor should
be consulted before taking any if he's on other medications.

Hello Debbie,
   Sorry for the problems developed with use of injection.  I admit they
are not easy, and not for the light hearted.
I understand Cialis is very similiar to Viagra, and I may be wrong.
Why not try less invasive and use a pump for a while.......No headache, no
skin rash.......
The pump is fine, and I admit it is clumsy, but can be used with sexual
foreplay and stimulation.
The pump also provides blood flow to the affected area, and that is
important.
My wife helped me, and with the use of the pump and was never at all ashamed
at me trying....
Maybe down the line, and with all the exersize, things may start to work.
It happened to me!  Took 2 years, a loving wife, many injections, headaches
from viagra, and pump......
After all said and done, I made it through yet another hurdle life puts in
front of you!
Good wishes, keep trying....
John Loomis
