I've taken cialis 5mg an experienced muscle spasms. Does anybody else have this problem?

I had significant back pain and almost gave up on Cialis. I powered through and took Advil for several weeks and now, no side effects at all. Consider lowering your dose to 2.5 one, or maybe twice per day.

I took Cialis for a very short period of time about five years ago, and I have to stop because of severe back pain.

Muscle pain (known as myalgia) -- up to 4%; pain in the arms or legs -- up to 3% of people who take Cialis report these side effects.

You muscle spasms could be due to the side effects, please do speak to your doc/pharmacist who prescribed the med for more details if the spasms are too bothersome.

Take care, best wishes!
