<s>[INST] Hi   I am a 47 year old woman with high creatine in my blood when they draw it from vein they seem to think its from to much exercising so they told me to slow down a little then come back for more blood work when I do its still high I have had kidneys stones 2 different times and passed them on my own I myself don't think  its from exercising I have always done this I have arthuritis which they think might be causing it I would really like to know what kind of test they could do to figure out for sure whats going on with me I feel like something is eating away at my muscles tired of worrying [/INST] Hi and thank you so much for this query.From the inforation you have provided, I am concerned that your kidney stones may be interfering with the normal kidney function leading to increased levels of blood creatinine. i would suggest that you meet a nephrologit to evaluate you fully and address these kidney stones as the possible cause of your worsening renal function.Also, many electrolytes and substances lie uric acid are eliminated through the kidneys. I wouldn't want to immediate conclude that this is the reason of your arthritis but your doctor should look into this possibility as a possible cause.I hope this information proves helpful to you. For now, drinking much water would be of help but the best thing is to seek a nephrologist consult to address any possible cause. Also, doing tests would be guided by the various findings on physical exam. So get consulted first before we start asking for test that would be otherwise not related to your problemI wish you well as you take on this issue. Feel free to return to e with ore questions on this. I wish you the best of possible outcomes.Dr. Ditah, Md </s>
