I have tenderness at the very base or just below
Can be due to coccydynia.
Thanks for posting your query.
Pain at the very base of spine can be due to coccydynia- pain in coccyx. It is caused by inflammation of the coccyx bone. The symptoms are generally worse when sitting for prolonged periods of time, or with direct pressure to the tailbone area.
Follow these measures for relief from the symptoms:
1) Avoid sitting down for long periods of time. When seated, do not sit on hard surfaces and do alternate sitting on each side of the buttocks. Also, lean forward and direct your weight away from the tailbone.
2) Take adequate rest and apply cold compresses, avoid any injury to the affected area and take some antiinflammatory and pain medications like ibuprofen(motrin) or diclofenac. Some severe cases with persistent coccydynia are treated with local cortisone injection and surgical resection of the coccyx.
3) You can also use a "doughnut" cushion or pillow to sit on. This cushion has a hole in the middle of it to prevent the tailbone from contacting the flat surface.
4) Also eat a high fiber diet foods to soften stools and avoid constipation.
