Throat/ Clavicle Pain preventing cleans/ overhead oly work
About a month or two ago, when I was doing a lot of overhead work with a non-rotating bar and lowering a lot of it back to rack, the base of the left neck muscle started to swell where it attaches to the clavicle. I think I caused it by catching a lot of split cleans in an uneven rack position (left elbow lower than my right), and the strain just built over time, so I am trying to emphasize even, high elbow height in all exercises that involve holding the weight in front. I first noticed this when I started getting light-headed/ edging towards passing out occasionally while doing push-presses or jerks, which used to happen to me only once in a blue moon. Then, about a week and a half ago, without any acute strain or notable increase in training volume, it worsened to the point where I couldn't clean more than 90 kilos without experiencing enough pain to make efficient technique impossible. It only hurts when I'm catching something heavy on it.
I have laid off dynamic work from the front (cleans, power cleans, push-presses, jerks), switching all of my overhead work to the back and emphasizing a tight rack in my front split squats and overhead presses to keep the bar from resting on the trouble spot without support.
Does anyone have any experience with this kind of an injury or have any advice about how to work around it and prevent its recurrence?
