<s>[INST] I have been having excruciating pain in my tailbone area for 5 months now.  I haven't fallen or bumped into my tailbone, nor have I ever had any back injury's.  I have tried a donut to sit on but that doesn't help.  My tail bone hurts when Ilie in bed, when I sit and especially when I get up from a chair.  What can I do? [/INST] Hi there,welcome to  HCM,  thanks for the question. Tail bone pain is probably one of the most tricky situation to deal with, both for the patient  and the treating physician.Conservative meaures form the mainstay of treatment in almost all the cases of tail bone pain.This includes use of doughnut  (religiously in all situations)sitz bath (Sittingbourne a tub of water- similar to aquatic therapy), medications.If no relief with this prolotherapy which is injection of saline with locall ansthetic and/or local steroid injection  can be tried.Injectionseen can be repeated twice or thrice if thee is relief with first injection.Since your pain has been present for more than 5 months, it is unlikely that conservative measures  would help.Another evaluation with xrays and MRI might be warranted to investigate the source of your pain ( since there is no history of injury in your case) .In unrelenting pain rarely surgery would be a consideration  But unfortunately  even surgical results of coccygectomy (removal of tip of tail bone) have been found to be less than satisfactory for tail bone pain.Hope this answers your question..All the best with best regards.Dr.SBK </s>
