My new client gets head pain next to the left eye when ever she starts to train?

Any pain is an alarm signal. You write that it gets to the point where you have to stop training her. Since this has been pattern in the past, I also would not train her unless she has clearance from a doctor. This kind of pain needs medical attention, and the sooner the better.

No brainer, Doc visit asap!

Go to the doc dude! C'mon man!

You should have her see a Doctor. Pain is an indication that something is not right, as an Otologic Technician I see this often. It could be any of number of things including her Vestibular System.

If the doctor has no significant findings or labels it as a tension headache. Try teaching her stretches that release common trigger points at the upper trapezius or splenius capitus, that refer to area around the eye. Forward head flexion alone or lateral rotation to about 35-45 degrees with forward flexion may help.

She should go see her physician and get a full physical, including a stress test.

I concur with all previous answers. Pain and especially recurrent pain while exercising is an absolute indication for a need to consult with a doctor. In such a case, I would stop working with that client and obtain a new medical clearance for exercise participation while specifying on the form your client's signs and symptoms during exercise. I suspect hypertension, possibly in the eye. It could be precursor signs of a stroke. Either way, best not to play doctor and urge your client to see a one before resuming his/her program with you.

I don't concur with all of the answers. I also don't know all the answers. But before people JUMP to saying refer to MD.

We need to think, stop and assess what the client is presenting with while always remember safety.

You have to determine the quality of pain, intensity, severity. First and foremost. Yes eye pain is serious but is it intermittent or constant.

Constant eye pain particularly acute or chronic should not involve and exercise and the client should see a MD.

Intermittent eye pain particularly if the client says to the side or "behind my eye" can replicate
cluster headaches that the client will describe almost a ring around the eye.

Typical epidemiological features of cluster headaches are:
more common in males, may last 2 weeks to 3 months in duration, they occur at night, characterized by trigeiminal nerve pain, associated symptoms are nasal stuffiness, ptosis.
Easing factors: ice compress, diaphragmatic breathing and relaxation techniques and sitting upright.
Aggravating factors:stress, alcohol consumption, fever, bright lights or glare/

Pathology of condition: per the literature is a biochemical and neuro inflammatory process in nature.

Physician typically refers sumatriptain for acute attaches.
Mgt strategies such as smoking cessation, lifestyle modifiucation are key.
