Hi

Thanks for posting your query

With the brief history you have provided it appears there is some problem with the excretion of the water that you are consuming

Your symptoms of feeling huge, having headaches and bodyache along with the problem of not being able to pass urine, point to something wrong with your kidneys

Your Pharmacist is right, you should consult your physicisn and go ahead with getting reports done to rule out kidney disease

A word Of Caution : Do not take water pills [I presume you mean diuretics] without getting yourself evaluated and without medical supervision

Hope I have cleared your doubts, If yes accept my response or in case you need any clarification revert back

Get Well Soon
