Exercise Type: Run

Comments:
I felt like a fog had been lifted on my run today. For the first time in about two weeks it felt good to run. It was like I had forgotten what it felt like! I think it's because, after yesterday's epic disaster, I stopped taking the twice daily 800mg of ibuprofen that I had been on for about the past 10 days. The bad thing though is that my chest pain was very noticable today, worse than in the previous few days. I cut it short because I was worried that I was causing it too much inflammation. It feels like someone's pinching my heart and lungs or poking them with little needles.

Anyway, I don't know what I'm going to do from here. It's like I went from being a 22-minute 5ker yesterday to a 20-minute 5ker today. Still a ways to go.

ibuprofen can have some nasty effects on your kidneys, especially when exercising. Here's some stuff I've found on the topic:
"When a muscle breaks down or is injured, myoglobin is leaked into the
bloodstream, which carries it to the kidney....There are substances in your
body called prostaglandins which cause the blood vessels flowing into the
kidney to dilate when necessary, increasing the blood flow to the kidney. The
prostaglandins will ordinarily do this when the kidney is under attack from
myoglobins. However, it is known that NSAIDs, such as ibuprofen, inhibit the
action of the
prostaglandins, thus allowing the myoglobins to do their nasty business
unimpeded."

also,
"All organs and tissues need Oxygen. It is delivered to the those organs by the
blood. Red blood cells (RBC) in the blood are the 'box cars' to transport the
oxygen. If there is not enough RBCs then the oxygen delivery system will be
inadequate. Kidneys monitor such 'trafficking of oxygen.' If kidneys sense
that less oxygen is being transported, then they try to add more 'box cars'
(RBCs) to the blood to carry more oxygen. The kidneys do it by producing more
of a 'bone marrow stimulant' called Erythropoietin. Erythropoietin stimulates
bone marrow to produce more RBCs."
also,
Kidneys regulate blood pH. Once in oxygen-debt, lactic acid begins to build up.
The increased amount of lactic acid in the blood stream would require increased
action from the kidneys to regulate it. Oxygen debt would further be exacerbated
by an inability of the kidneys to increase EPO production.
