Last year, about this time, I developed lithium intoxication. I really don't know why this happened. Perhaps it was a very bad fall that I took while running which left me unconscience. I had been taking lithium for over 30 years, monitoring the lithium level in my blood every six months. The intoxication caused me to be hospitalized for almost a month with chronic kidney failure and extreme dehydration. Now the nephrologists tell me that I must follow a strict diet, but none of them gives me a complete list of food to avoid and food allowed. Of the few foods that they mention as not allowed are tomatoes. I get most of my information on these foods from different places on the Internet. However, I eat a salad almost every day with small amounts of diced tomatoes.

I can't tell exactly where my kidneys are, must less the left or the right. You seem to be able to distinguish this --- you're lucky.

Unless you eat great amount of tomatoes, I doubt whether some modest amounts will harm you. It's not the tomatoes themselves that are harmful, it's the potassium that they contain.

Good luck in "San Antón".
