Front thigh pain is a result of compressed nerves coming out of the spine or the facet joints. An RFA or an RFI will stop that front thigh pain. When no medicine will. I can’t tell you the stupidity of the medical system when people don’t understand referred pain. I am sorry you are not getting the attention you need to deal with that, if you can still have an RFA or an RFI your facet joints then I suggest you find a pain management clinic that will do it. There are two kinds and pulse, and only the heat worked for me and sometimes you have to have it done twice before it really steps , but for me, it stuck for 15 years the first time and then three years the second time and that’s when we all knew that I was ready for surgery. They should diagnose you which level in your spine is causing your pain each area that you get referred into , correspond to a different nerve root coming out from your spine or facet joints. In other words your pain management doctors should be doing diagnostic treatments to determine exactly where the pains originating from it’s not coming from your thighs.
