Hello,
I'm sorry to hear you developed
back pain while using
Cialis. Back pain is a known side effect of Cialis, and the drug can have effects on your body up to about 3 days.
However, given that it doesn't sound like your back pain has improved at all, and because the pain goes down to your feet with some
numbness, I would be suspicious that something else is causing your back pain, perhaps a
nerve impingement in your back.
I would suggest seeing your doctor about it, he/she might be able to start you on some inflammatory medication and
physical therapy which might help with the pain. I hope that helps and that you can relief from the pain quickly.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Aaron Branch, General & Family Physician
