I have discovered a most likely solution the case study of the woman in photo attached is exactly like my case. And she had an injection directly into the coccus and had total relief. Most experience a 50-75% reduction in pain. A local pain clinic here in Toronto has 2 doctors who do this routinely and my dr has sent a Referral. Hopefully I will get it done before my Africa trek in June climaxing with a gorilla trek in Uganda. If not the African roads will kill me.
