Pain above my elbows?

I've been climbing off and on for about two years now, and have recently gone from climbing short sport routes (5.9-5.10) a few times a month at most, to bouldering in the gym (up to v2 and a few v3s here and there) a few times a week. Now after my sessions, I'm getting a dull, achy pain in the pink area on the left arm in the image.

That is, with my palm facing upwards, the pain is located on the upper, outside part of my bicep, starting about one inch above the elbow and ending about 3 inches above that.

I haven't experienced any pain during climbing with this, it only occurs once I have stopped, and it goes away if I continue climbing on some easier problems, but returns again once I stop.

Is this Tennis Elbow or something else?

Although your picture appears to be the peripheral nerve distributions your pain fits a dermatomal pattern. Specifically the C5 nerve root. Or it could be something else entirely. Any neck pain or history of neck pain? Any good PT should be able to help you out.

I do have scoliosis, a s curvature. I used to have problems with my lower back muscles getting very tired that I believed to be the cause of odd pains in my left leg that would only surface when my back was tired, but doing yoga seemed to fix that.

This makes 3 nagging slightly painful injuries now, the tendon in my left foot that connects to my big toe bothers me after long runs, my left wrist and now this.

Maybe I can get some sort of discount if I take all three to the same guy heh heh.

Would it be better to go to a PT or to find a sports medicine doctor?

McKenzie trained physical therapists treat a lot of nerve root irritation. A sports medicine doctor will likely send you to PT anyway if you do in fact have an issue with C5.

As far as scoliosis is concerned, the only conservative treatment I've heard of (provided you're done growing) is the Schroth Method. I've never seen it done but have heard good things:

Also, I've remembered that occasionally if I lean my neck far enough forward, I can produce pain in it. Though I am unable to do this with any consistency, and it is very rare that it happens.

If I remember correctly the pain does come from right around C5 though.

The pain in my elbows is completely equal, except after it mostly goes away, one side or the other will ache for a few seconds, and it seems to linger on the right longer than the left. Ibprophen or naproxen sodium seem to make it go away faster.

Does this change or support your suspicion?

Nerve root irritation is usually unilateral.
