Wow, that's definitely concerning. I understand getting the injections for pain, but don't know if I would have a second one without a good explanation of the weakness from the first. I have had combination steroid/lidocaine injections a number of times, and can't remember a weakness issue, and the falling is very concerning.
Another concern is the breaking capillaries - not sure what it suggests, but may be related to the amount of steroid being used, or your particular response to the drug.

I am very particular, and only trust my orthopedic (hip) surgeon and my long-time primary provider - I have had too many times when the injections were too painful and/or ineffective when done by others. I even refused to allow my hand surgeon to do an injection in my thumb, trusting his ortho partner more. I was a little worried he would be offended, but he understood - said he had seen too many people with bad injection stories.

Who is doing your injections? Is it possible for you to consult with someone else about what is going on? Are you having injections in hopes of postponing hip surgery?
