I have had back pain (and chest pain) since 2007 when, of all things, I stepped off a kerb that I misjudged the height of. Since then I have been through all sorts of tests (x-ray, ECG, stress ECG, LFTs, Ultrasounds, Gastroscopy, Manometry and, finally, an MRI - the result of which was that a nerve trapped between T4 and T5 verterbrae of my spine was causing the chest pain and nothing much can be done about it as it's too dangerous.
That left the back pain - which is in my lower left back only, and is worse when I move while lying down, or when I'm getting into the car seat. Also my left hip often seems to grind (and I have clicks and pops) when I walk.
I also have two obvious lumps, like described above, in my left back, one near one of my ribs and one closer to my waist - and I always thought these were causing pain.
I visited my GP today (I'm in the UK) after opting out of the medical system for a while due to getting a bit down about it all, and I told her about these lumps and she prodded and poked. She didn't seem overly concerned about them to be honest, which I was disappointed by.
For the hip grinding she says she will refer me to an Orthopaedic Surgeon. However, ideally I want these fatty lumps gone too - it can't be coincidence that they're in the same place as the pain.
