Weaver bottom is due to bursa formation at the buttocks bone ie Sichuan tuberosity, to reduce pain you have to reduce pressure on buttocks ,keep cushions while sitting

Have you met an orthopaedic surgeon? Has an xray been done? Where exactly is the pain? Most common cause is coccydynia..inflammation of the tail bone..usually it helps to use a sacral cushion while sitting and avoid sitting on hard surfaces. Avoid using the medication as they don't treat the underlying cause. Hifenac is ok for acute pain relief. Other two tablets better to avoid
