Hip/Lower Back Injury

Yes, I am going to see a doctor.
No, I am not seeking medical advice on an online forum.
Yes, I am going to die.

With that disclaimer out of the way, looking for information on hip and lower back pain. Here is the summary:

1) Active 34 y/o (ski, climb, train, lift, etc.)
2) No prior injury
3) No trauma to area (no loud pop during heavy lift, no ski accident into a tree, no highball falls)
4) Pain just sort of appeared one day and is really located to the lower back and hip area on my right side
5) Pain is a sharp one that comes on with certain movements (i.e. bending forward, sitting up from prone, twisting).
6) Doesn't impair climbing, skiing, working out, or walking. Really just a sharp pain that happens with specific movements. The real downside is that my body is starting to train itself to avoid those movements.
7) No constant pain. No pain when at rest, no dull ache.

My guess is some type of soft tissue injury to one of the many lower back or hip muscles. The inflammation is likely pissing off various connected or nearby muscles. Also, could be from sitting too much (I work on a computer all day) and tight IT bands/glutes/hamstrings could be pulling something out of whack?

Anyone ever experience anything like this? Just looking for some anecdotal information before going to see the doctor tomorrow.

I have a similar history and similar pain and went to a physical therapist.  She did a bunch of tests and it turned out I a had a random super weak butt muscle- the gluteus something or other.  I did some PT and it seems much better.  I also saw a doctor and he said it was probably a soft tissue injury.  

Tim, any chance you remember the name of the muscle that was weak?

JSH, thanks.

I actually do yoga daily. My first thought was the same as yours, tight hip flexors. While I'm not eliminating tightness in the hamstrings, glutes, and piriformis as a culprit, I stretch pretty religiously. It's entirely possible I'm stretching the wrong things, but wouldn't the tightness you're talking about be on both sides? This is right side specific.

Have you tried pouring coffee on it?

Sounds more like a nerve issue than soft tissue. rubbing cocaine on the affected area worked better than coffee imo.

I think it's the gluteus medius.  I do a lot of yoga too, as well as strength exercises, and was only bothered on one side (though it was my left side).  For whatever reason that particular muscle was weaker than everything else around it.  Probably I was compensating for some other injury and inadvertently caused another problem!   The pain was the worst after sitting, after standing up and moving around it would sort of go away.

Try using a foam roller if you haven't already, worked for me for a similar issue.

IMO this 100% psychosomatic, and i mean in a textbook way. I've had the exact same thing and cured it completely by doing nothing at all.

You are conditioned to have pain when doing a specific movement. So the pain comes back when you do it

The problem with doctors is that they might find something abnormal and assume the pain is coming from there but it's actually not. Read "The great pain deception" from Steve Ozanich or "Unlearn your pain". Worth giving it a shot unless you feel insulted by what I am saying
