Hello Margie, muscle weakness and cramps can be a side effect of the diuretic but I haven't heard it described as tingling, tightness or tenderness. Perhaps, as you suggest mention to the Consultant when you next have your appointment or if you see your GP first. Have you suffered from any low back pain or sciatic pain in the past perhaps?
Does the tightness and tingling include cramping of the foot or toes? Could be a Magnesium deficiency per my doctor. If I forget my evening Magnesium supplement, it gets worse.
I think we all have a tendency to think everything unusual with ourselves is CKD related. Every ache, pain, twinge, etc., we immediately think "it's the CKD", "somethings wrong". I do it too. It's probably a normal reaction. But I doubt what you describe is the CKD. It was interesting to read you take a diuretic. I took one for years. The moment I was diagnosed as CKD the doctor said "no more diuretics". My urologist said the same thing. I was at the time taking the diuretic with 20mg of lisinopril (2 times a day). It caused me some troubles with my blood pressure to stop the diuretic. It went up. not to danger levels but certainly too high. upper 130s. It took about 3 to 4 months to bring things back under control, experimenting with different medications. Finally we ended up with a combination of amlodipine 2 times a day, lisinopril 2 times a day. This brought my pressure too low!. So we ended up cutting the lisinopril in to just 10mg once a day, and amlodipine 2.5 mg once a day. You might want to suggest to your doctor about stopping the diuretic and seeing if this sensation you have goes away.
no swelling without the diuretic. But the diuretic for me was initially prescribed simply for blood pressure control. Not because I was at that time experiencing swelling. With the CKD they advise me to drinkg 60 to 70 ounces per day of water (at least). There was initially concern this might cause swelling if I did not take the diuretic. But fortunately I have not had a problem so far. Certainly there are times, and yours may be one, where for other medical purposes (not because of CKD) you need the diuretic. If you do stop it, be sure to take your blood pressure 2 or 3 times daily (always at the same time of day) to ensure stopping it does not increase your pressure. And of course you will be monitoring if it causes swelling increase, in which case you will start the diuretic again.
