I am sensitive to salicylates as the result of overuse of Ibuprofen (chemically very similar to aspirin). I developed asthma-like respiratory symptoms when eating certain foods but couldn't figure out which foods were responsible. Then I developed paresthesia in my left thigh when I took a non-steroidal anti-inflammatory drug which was prescribed for back pain. Ironically, all of the muscle pains etc. disappeared once I removed everything from my diet that I was sensitive to. - USA [Commonly called 'pins and needles' paraesthesia is a sensation of numbness, prickling and tingling that is normally felt in a limb or extremity.] - USA
