This is the gist of my problem:
lower back pain noticed (spasms or lower back "lock ups") brought on by taking high amounts caffeine, diet pills, supplements containg green tea extract, taurine, ephedrine.
Here is a more detailed explanation:
recently I had begun working out again (2 months ago) after taking a couple years off. I had developed a pretty good routine 4-5 days a week that was a healthy mixture of cardio and weight lifting.
My wife for christmas wanting to "help" my work out routine, went to the local gnc and talked to the clerk there. He recommended I take two supplements that would help my workout. These supplements are heavy in taurine, green tea extract and protein. One was a shake, the other were pills (2 pills a day is the recommend dose).
I took both supplements in the morning (i do my workouts at night) and on the drive home from work I noticed a dull ache in my lower back and kidney region. This lower back pain progessed until it was time for my workout, which is right around 8pm at night (i took the supplements almost 13 hours earlier at 7am). I began with a mile jog, went to three sets of bench press and began to run again. During my second run my lower back spasmed heavily and "locked" up on me. I could barely walk. I ended my routine, went home and noticed an hour later that the lower back spasm tailed off to a dull ache. This was two days ago and this dull ache in my lower back kidney region has been with me ever since.
My history:
this is not the first time this has happened to me and I wonder if my abuse of ephedrine pills when I was in my early 20s (taking 10-16 pills a day off and on for a month or two) has played a part in these lower back kidney pain episodes. I noticed after two months of this on and off abuse of ephedrine I was starting to get lower back pain - this bothered me because my grandfather had passed away in his 50s as a result of kidney disease. I immediately stopped taking the pills. The lower back pain went away.
When I was 27 I began working out pretty heavily. I was a bit overweight (50 pounds heavier than I am currently) and I mixed my workout with diet pills (hydroxycut to be exact). I did not abuse the diet pills, but in fact followed the daily recommend dosage. While using the stair climber during one of my workouts my lower back spasmed exactly like it did two days ago and I was out of operation then (no workouts) for days, if not a week or two if I remember correctly. The lower back pain stayed with me for a week.
My questions:
is this lower back pain brought on by heavy amounts of caffeine stimulants? If so, why days after i've taken these supplements do I still have a dull ache in my lower back? Did the heavy spasm I experienced during my workout pull the muscles in my lower back?
-or-
is there truly something wrong with my kidneys? I have no blood in my urine (it's always been dark in color though)
my doctor's opinion:
i told my doctor about all of this a year and a half ago because I was worried I may have damaged my kidneys because whenever I take high amounts of caffeine I would get lower back pain. She was not concerned. I have searched high and low on the internet and I can't find any legitimate connection between ephedrine abuse, caffeine consumption, and diet supplements that lead to lower back pain.
Your input would be greatly appreciated. Thank you in advance.
