Surefire way to reduce blood pressure without drugs

Almost by accident I've discovered that running temporarily reduces my blood pressure significantly: I've measured by before and after blood pressure 4 times now and in each case it's dropped from around 130/80 to around 115/70 (or less) after running ~2km (~1 mile) (which is around 10 minutes running for me). The effect only lasts a few hours but I'm guessing that running twice a day could help a lot in keeping the pressure down, and thus reduce the damage to the kidneys from high blood pressure. My only problem is that as well as chronic kidney disease, I also suffer from chronic laziness... but I guess it's just a matter of acquiring the habit.

The dangers of Internet diagnosis

The last month I have been suffering horribly from itchy skin, mostly in the legs. Because there were no visual signs at first, I self-internet-diagnosed the itchiness as a symptom of poor circulation (a few months ago I was diagnosed with a probable small blood clot in one of my legs). My doctor for circulation issues is located about an hour's drive away and in any case had no appointments immediately available so I self-medicated by doing exercise (to improve circulation) and applying moisturizing cream to reduce the itchiness. Unfortunately, over the weeks, things worsened until the itchiness spread all over my body, in patches of visible spots, and so uncomfortable it was interfering with my work and leisure. Now it was obvious that this must be some kind of skin issue and probably not related to circulation or my kidney disease (which can also cause itchiness in the late stages). I called my usual dermatogist. Next available appointment in 6 weeks. I'd probably commit suicide by then because the itching was driving me crazy. Managed to get an appointment with a general practitioner who swiftly diagnosed the problem as scabies, a microscopic parasite whose larvae burrow into the skin. While relieved to find I had a treatable condition, I felt like such an idiot for suffering for so long just because of my general reluctance to organize a visit to the doctor. Moral of the story: SEE AN EXPERT as soon as things start getting worse! Second moral: Those of us who have easy access to healthcare are unbelievably lucky compared to the most of the world's population. We should appreciate that and not take it for granted.
