It sounds like you have a tendonitis
or a bursitis related to both of your biceps tendons although this is somewhat unusual. You are doing all of the right things. You may want to be assessed to make sure that your tendons are intact and you have not rupture them. I would go and see a physiotherapist would can offer pulsed ultrasound
treatment as this has been shown to be beneficial in cases of tendonitis. An orthopaedic surgeon
may be willing to inject local anaesthetic
around the tendons if your symptoms are ongoing although tis would carry with it a risk of tendon rupture.
