I took cialis 2 nights ago and still have affects from it.?

I've had headaches and couldn't sleep last night due to a pain in my right leg. I'm completely stuffed up as if I have a head cold. Anyone know how long it will take to wear off? And why would this be so accepted if the affects are so strong? Meanwhile, I have had an erection for the last 2 days on and off so that part worked well but I'll discontinue use solely for the side affects.I took cialis 2 nights ago and still have affects from it.?
You should see a doctor, the pain in your leg is more worrying than the headaches...its could be a blood clot.
Go & see your doctor asap.Hope your feeling better.
