Hello, Five or six hours ago, I had a small bowl of cashews. Fairly soon after having them, I felt mildly faint and tingly, so I decided to keep my cell close by and make sure I didn t fall asleep. I m feeling back to normal now, so my questions are whether it s likely I ve randomly developed an allergy (I m 20, and have been taking 0,5 mL of Delatestryl every other week for nearly a year, in case it s relevant), and how long I have to wait until I know I m in the clear, allergic-reaction wise.
