View Full Version : Calf Pressure when Running

05-08-10, 04:38 PM
I am an avid runner and have been training for a half marathon for the last few months. I usually run later at night and have been doing anywhere between 5-10 miles without and pain or fatigue.

Today I went for an earlier run after taking my medicine and noticed an immense pain/pressure in my mid/lower calfs at around mile 2. It is very frustrating as my training had been going very well.

I was wondering if anyone else has noticed any similiar effects when taking this medication? I am on Focalin XR 20mg.
