yesterday i saw the consultant for my underactive thyroid and at the same time he tested my waters. There was protein found in the sample and they said they were sending it off to the lab to be tested further. Last night i was out of bed so many times for the toilet, my bladder hurting, feeling like i need to pee alot more than what is actually coming out, back ache... got alot of the symptoms to relate to a water infection. So this morning, i called my doctors to see if they could get the results back asap and they said bring them a water sample to them straight away and they will test there and then and subscribe some anti-biotics. I did this and they say the water test is all fine today..... What else could be wrong with me do you think? Anyone experienced this?
