My wife seems to be having a bad allergic reaction. She has rashes all over her body and is itching badly. What is the best way to alleviate this?

Stop the offending: Cause if known. Also reasonable to take short acting antihistamines like Benadryl (diphenhydramine) or longer acting ones like Claritin or Zyrtec. If the rash is severe enough and/or the itching is not alleviated than over the counter steroid creams may be beneficial. Of course if symptoms do not improve or worsen a trip to the doctor may be in order for a definitive diagnosis and/or stronger prescriptions. ...Read more

I smoked weed for the first time and I woke up in the morning with rashes on my chest and chest pain, is this normal? Is it an allergic reaction?

If the stuff does become legal and you want to resume, remember that there may have been something else in that particular batch that "wasn't supposed to be there." experiment again only at your own risk. ...Read more

My baby's body rash is getting worse. Concerned it might be an allergic reaction to almond milk. What should I do?

My baby's body rash is getting worse. Concerned it might be an allergic reaction to almond milk. What should I do?

Don't worry: First don't stress out. Babies get rashes all the time for various very common reasons. Second, why are you giving almond milk? You can stop it if you'd like. This may provide data as to whether or not it is involved. Third, take photos of the rash progression and see the pediatrician because only eyes-on can really determine the type of rash. Could be allergy; I'd sooner blame a virus or eczema. ...Read more
