Your biceps are the reason you can bend your arm and touch your shoulder, and we use them every time our arm goes from straight to even a little bit bent…basically we use them 98% of our life, even while sleeping. With this much use it’s not surprising that they can stay shortened due to muscle memory. The fibers have been held short for an extended period of time and they just can’t lengthen properly. This will cause tension at both ends of the muscle so your inside elbow joint will hurt when you try to bring your arm straight out, and the tension on the other end at the shoulder is a bit more complex and far-reaching.
Your biceps have two heads (originating points), one is inside your shoulder joint. While it’s not a part of the rotator cuff, tension on this muscle causes pain deep within your shoulder joint and you may be diagnosed with a rotator cuff injury. The other head is on a tiny bone, called the coracoid process, that is a part of your shoulder blade.
The carocoid process crosses directly over your artery and all three nerves to your shoulder, arm and hand. When the biceps are tight and pulling down on the bone it puts pressure right on the nerves and artery so you may get cold fingers as the blood flow lessens, or tingling/numbness into your arm, wrist and fingers. In fact, when your biceps are pulling on the carocoid you may even be told you have carpal tunnel syndrome, so it’s worthwhile self-treating them. Even if they aren’t hurting at the moment you could easily be having other symptoms that are being caused by tight biceps and that you aren’t relating to this tight muscle. Another important point is when your biceps are in spasm you will lose strength in your arms, so treating the spasms and stretching will increase your strength.
