Does Nurofen drug treat allergic capillary inflammation cause complications?

Question
Hi Doctor, my 14 year old son has allergic capillary disease. Taking nurofen as prescribed for 4 days now, but every day I have abdominal pain, the first day I had a red rash in my legs with joint pain in my legs and stomachache, and this morning the red spots appeared on my hands. So please ask the doctor if this is a complication? Thank you doctor.

Hi, the most common symptoms of allergic capillary disease include: Purpura in the form of dots or nodules on the flexors of the forearm, lower leg, buttocks, thigh ... no itching, joint pain, edema around the joints, abdominal pain around the navel, dull, constant pain, vomiting and nausea, may be accompanied by gastrointestinal bleeding, glomerulonephritis, hematuria, proteinuria . You need to monitor the child continuously and take him to a doctor at Pediatrics if the symptoms increase. If the disease is left for a long time, it will affect organs such as the heart and lungs, causing severe symptoms, difficult to treat and dangerous.
