Hi. Thanks for your query. Noted the history and understood the concerns. Loosing weight of about 15 lbs over 2-3 months, diarrhea and sometimes blood on wiping may be connected as anything related to small and large intestine will not allow all the nutrients to get absorbed hence can not maintain the weight. Lump in the right leg where lymph nodes are may be due to lymph node. There is recurrent nose congestion that can be due to seasonal allergies or vasomotor rhinitis related to the stress and anxiety. I would advise you the following: Get the problems diagnosed one by one and to get the proper treatment for all. To begin with the most important problem of diarrhea that might have been the cause of weight loss. Get the stool tested, ultrasound of the abdomen, CT scan and colonoscopy along with other tests of blood and urine to complete the search for the cause to be aided with proper clinical evaluation and examination to get the proper diagnosis and have proper management. Ultrasonography and FNAC of the inguinal lump to get a proper cause and get treated accordingly. ENT consultation for the congestion and get proper clinical examination and investigations to get the proper cause and get treated accordingly., Get started on proper supplements.
