Ouch!

This week's swimming has caught up with me today. My left shoulder feels stiff and almost that I don't want to move it in case it hurts. My left forearm rotator muscles and the tendon insert are sore and even pain extending into my biceps. My right arm is OK, although it does feel 'worked'. I'm not sure if this problem is due to the set of swims this week or more specifically due to Saturday's swim when I was trying to do some shoulder extension - that will have worked deltoid muscles and pulled the joint to its limit of movement. I'm disappointed that the elbow pain reappeared strongly as I thought I was avoiding that load.
