Patient discussion about react

Q. can one be allergic to multiply things and react the same?

A. if you are allergic to something that means you have a tendency to develop allergies. Your body can decide to react in the same way to other things too. It can also manifest in other way- depends on the allergen. If it's airborne, could get to bronchi and cause asthma, or to the nasal cavity and cause sneezing and mucus. Or if can cause irritation by touch. Any way, the answer is yes:)

Q. Why do some people react differently to alcohol than others? Why do some people react differently to alcohol than others? I am one among those ‘some people’.

A. Hi friend. Before I answer your question, I need an answer from you. May I know how you react ‘differently’? Usually, the individual’s reaction to alcohol will vary. They are influenced by many factors, including but not limited to:

• Age.
• Gender.
• Race or ethnicity.
• Physical condition (weight, fitness level, etc).
• Amount of food consumed before drinking.
• How quickly the alcohol was consumed.
• Use of drugs or prescription medicines.
• Family history of alcohol problems.

Q. How bad can a infection get in your body? Like if you react to something like condoms and dont get it treated. I had a reaction a year ago to 3 condoms that were used and I didnt get it treated,not everything is weird in my area. Like, im all papery down there and stuff like that. And please dont say go to the doctor because that doesnt help me at the moment, because right now, thats impossible to do and please dont ask why. Thank you.

A. what you describes sounds like you had an allergic reaction to latex. an infection might be caused afterwards- if the skin ruptured. because i can't look (and please refrain adding or sending a picture- my wife can understand it the wrong way :) ) i can't really tell you if it looked you see puss? in not- get a moisturizer and use frequently. if there is an infection- there are antibiotic creams but they need a Dr. prescription if i'm not mistaken.
