Hoping someone can help put my mind at rest as I can feel my anxiety running away with me. i've been having some problems lately with heart palpitations and mild niggling pain in both sides and gallbladder area. Nurse at gp practice sent me for blood tests (don't know what specific ones as I wasn't told and didn't ask). I phoned today for results and the receptionist said they were all normal except for 'urea' which had been marked 'slightly outwith normal range' but the gp had said no further action required. I feel I should be relieved the doc clearly isn't worried about it but now my mind's running away with me that there's something horribly wrong with my kidneys due to this pain in my sides and near where my gallbladder is and I'm starting to notice things that are probably nothing like little bubbles in my pee (I know frothy urine is sign of kidney probs). Someone please give me a reality check and help me put my mind at rest that the blood test results are probably nothing to worry about.
