Hi, it goes like this
Hello, I will advise about avoiding processed food. As due to this you are getting acidity and due to which abnormal reactions. Feeling Chat Doctor.  Tingling in legs and arms aren't related to the processed food. It may be due to other factors and needs a separate examination and assessment. Joint pains can be due to inflammation and not related to processed food. As we aren't knowing your age and any underlying past medical history we can not connect the processed food with the current mentioned symptoms. Do some simple general exercise, so the metabolism improves, and you will also avoid processed food for good health. Hope I have answered your query. Let me know if I can assist you further. Jay In
