I have developed a very painful spot on the left cheek of my buttocks. I m not sure if it is a pressure sore or a fissure. I sit most of the time due to a bad hip, even have to sleep in a recliner. I have a very thick cussion in the recliner. I have applied Lantiseptic ointment, desitin diaper rash cream and triple antibiotic ointment. These products give temporary relief. I was wondering if a sitz bath might bring relief and healing. What are your suggestions.
