Re: Urine discoloration what does it mean
Ann has a good point--certain things you ingest can definitely cause the urine to change colour, though the triad of abdominal pain, peripheral neuropathy and a change in the colour of the urine (to a reddish colour which resembles Coca-Cola) is suggestive of acute intermittent porphyria. Have you ever been checked for this? It's an insidious diagnosis so a lot of the time it's not thought of...well, that and it's rare. However, a peripheral neuropathy in the absence of any other common predisposing factor is also not very common.
Weird things which can cause peripheral neuropathies other than porphyria include: sarcoidosis, certain forms of vasculitis, leprosy, lead poisoning etc. etc.
