Maybe, BUT: Check with your doctor asap. If s/he says you're ok, then consider the recurrent nature of this and what you are doing or eating that is a trigger. Food allergy and food intolerance symptoms come in all shapes and sizes. Everyone's different. Try a serious elimination diet, add some probiotics (long term) and let your body guide you to foods you can tolerate well. You may feel lots better.

No: Stroke is permanent. Transient ischemic attack (TIA) can have intermittent symptoms. Please see a health care provider for a complete history and physical and a further evaluation of your symptoms.
