Expert answer:
I know of your condition and abroad is always a little more difficult access to medicine, but I can not do diagnosis or treatment over the internet. Palpitations in young people statistically most of the time is associated with anxiety problems. Ibuprofen is an anti-inflammatory and as such it can do bad to the stomach if used in excess, however gastric problems and numbness in young people may also be associated with anxiety. Emotional problems are what we often call exclusionary diagnoses (excluding physical illnesses are left with only emotional problems), so consultation with a doctor is so important, to state that it is an anxiety problem, other causes need to be removed first .
