I have experienced swelling in my throat, mouth, lips and eyes. Twice, while the above was happening, my tummy area felt like it had alot of pressure,with noticeable swelling. While swelling is occuring, my legs, behind the knees, feel numb, kind of like they are asleep. I have been given an epi pen to help stop some swelling, but no diagnosis. It is terrifying so please assist in discovering cause. I have had allergy testing and seem to have reactions to herbicides,pesticides etc... I just want it to stop.
