Skipping has killed me.

Honestly, see those red lightening strikes, it's never hurt anywhere ever that much before.

 It's only come on in the past hour (so that's the reason I've not done any exercise all day), and it's quite literally only a two inch section at the very top.  It's excruciating.

 Does any one know, like biologically or anatomically damaged?  And if it's biological or anatomical?
