Hi I am 15yr  old female and earlier on this year i was diagnosed with hsp and already was on thyroxine now i also am on movicol, calcium and vitamin d. My doctor said hsp can cause kidney problems and since the hsp i have had 5 urine infections and had urine tested at every appointment i have had and since hsp there has always been blood in it.I also have a lump on left side of tummy, and occasional pain in my flanksnot gaining weight and constantly tired, even though i get really tired sometimes it takes me up to 5 hours to get to sleep at night.
Hello. Abdominal pain, joint pain and kidney problems are frequent in HSP. The presence of protein and blood in urine is common in patients with HSP. If a patient with HSP have lump in abdomen, with pain in flank is necessary to do an abdomen ultrasound to rule out renal mass. Please, go to your doctor as soon as possible to request an abdominal ultrasound. I wish you good health.(In case the answer would have been useful please indicate this)
