Brits symptoms and conditions

I was given a 2 Kenalog shots in my lower back to treat a pain in my sacroiliac joint, which refers to the front of my leg/groin area. My doctor barely examined me, I was sent for no scans or other diagnostics. He said that the shots should bring down the swelling. They didn't work at all and yesterday, a couple of months later I felt a significant indentation on my back - precisely at the injection site (just where my lower back meets the top of my buttock). I have also suffered seven weeks with no period, coupled with nausea (thanks for the pregnancy scare!) then very heavy periods. I am a migraine sufferer and my migraines have increased in intensity. I also have constant, painful eczema, where before it was sporadic and light.

I am not sure how many side effects can be attributed to the injection - but the indentation at least is a definite. I live in the UK - I wondered if there are any other Brits here who have had the injection, or anyone generally who had it in the same place as me - I'm worried about what happens from hereon in. Can it affect my mobility? The original problem (still undiagnosed, but after a year of begging I am being sent to a hospital next week - to a Rheumatologist - is that even the correct field of expertise?) causes me huge amounts of pain anyway.

I also have a great number of the conditions the doctor is supposed to make sure that you don't have - why did he just "do it anyway?" In the UK it is difficult to bring any kind of action against a doctor >:-(

I'm relieved to find this board - best wishes to you all :-)
