You are over reacting. Why continue to exercise the arm, which will only exacerbate problems and risk a repetitive stress syndrome, if you believe the tendon is injured?
Pulling tendon away from bone requires a great deal of force, and is very traumatic, usually accompanied with a loud snap followed by sharp pain and much swelling and bruising. You report none of these symptoms.
While the biceps tendon coincides with your red marks, what you describe sounds more like pulled muscles or at worse, a tendon rupture, which indicate you're using too much weight and extending too far out of the curl.
Treatment for either a muscle pull or tendon rupture requires rest, ice, compression, and elevation (RICE). NSAIDs can be used, but always take NSAIDs with food, and keep to recommended doses.
After 2 weeks of RICE, you can begin PT with small weights. By then your insurance will come into effect. However, If you experience an increase pain and swelling with RICE, you should see a doctor.
Someone please? Need I sound more desperate?
