I have been having pain deep on the lateral side of my right bicep whenever performing almost any kind of arm flexion. Heavier the resistance, the more the pain.I have realized now, my right bicep (dominant hand) is now smaller, flatter than my left bicep even though the right bicep has always been larger, fuller and had more peak than my non-dominant. Also discovered that I can no longer fully flex the right bicep isometrically (bicep pose) and is soft to the touch even at full isometric flexion. I do have full movement and most of the strength in the arm, its just the bicep seems to not be fully firing. No pump, no muscle/mind connection. No balling up of the bicep, so rupture seems unlikely. Also experiencing some brachioradialis pain as well.
Been icing 20 minutes twice a day which is helping. Gua Sha is pretty painful and seems to inflame the area. Might start some Voodoo Flossing.
My question to the board is has anyone experienced anything like this or do you have any unique tendonitis type treatments that you successfully used in the past?
For reference, I am a 44 year old, semi-retired bodybuilder with 25 years in the gym and around 20 competitions under my belt (to give you an idea of the mileage on me).
Thanks in advance.
