I flied from Dallas to Honolulu. After the flight my left eye had a black ring. One h day later the ankle of my left foot had big red patches with rashlike appearance. No itching, big surprise, was hot to touch. Redness did not go away, 7 day later I took 1.3 grams of aspirin within 1-1.5 hours. Next morning redness gone, too 650 mg aspirin the next morning, then 325 mg that night and following morning, on 9th day flew back to Dallas. Next day hematoma in left wrist. Every time no apparent reason for bleeding.My calcium pills have more than RDA of K2, my multivitamin pills have gingho biloba, but never before any problems. Is there a danger that I might also have undetected bleeding in my head/ brain?
