Trimeresurus,
I do not know what you have against Brufen, I have had osteo-arthritis for many years and took Brufen on a regular basis, with no ill effects ( I now take Voltaren , less dosage , better pain relief ). As with most medication , providing it is taken in accordance with the doctors/manufacturers instructions , like for Brufen with or immediately after food , generally there is no problem. I don't know whether, or not , you are medically qualified,( I am not), to call someone "a dangerous man " without specific knowledge is probably not a good idea. In all cases medical advice should be sought.
