My husband is a steady drinker. He recently had what we believe was an allergic reaction to drinking.. We have also recently completed a milk thistle based liver cleanse.Since the liver cleanse the problem has been ongoing. The first allergic reaction lasted 3 days. The symptoms included... Hives, itching,swelling of the throat, inability to swollow properly,swollen eyes,and a swollen itchy penis. The same symptoms have occurred each time since - less severe. It is very concerning and puzzling. He also becomes quite unwell when stung by anything - ticks,ants,bees,wasps.. hives and rashes, swelling also occurs when bitten
