Environmental Factors Behind Thyroid Disease | Wellness Clinic

The thyroid gland is a butterfly-shaped organ located in the base of the neck. It's in charge of releasing essential thyroid hormones which control the body's metabolism, the way the body uses energy. The thyroid gland's hormones regulate vital body functions, such as breathing, heart rate, central and peripheral nervous systems, body temperature and more.

What causes autoimmune thyroid disease?
As essential as the thyroid gland is, however, the body's own immune system can sometimes malfunction and attack this important endocrine organ, ultimately affecting its function. Autoimmune thyroid diseases, like Hashimoto's thyroid disease and Graves' disease, have been on the rise in the United States. While the diagnosis of thyroid disease has increased, many doctors still don't know the cause of the issue, but these have been linked to several factors.

Chronically Tight Calf Muscle: Scientific Treatment


Science chiropractor, Dr. Alexander Jimenez investigates the methods described in treating a tight calf muscle.

Assess The Calf Complex

In the calf complex, the medial sural nerve descends between the two gastrocnemius heads and also at mid-calf level combines with a branch of the peroneal nerve to form the sural nerve(1,2). As we get older, the body's connective tissue gets less pliable. Nerves are naturally surrounded by connective tissues -- sometimes they even run through connective tissues, so with aging the nerves can get trapped, trapped or tethered to surrounding muscle or fascia(3).

This can manifest as a feeling of tightness deep in the calf muscle that never changes, no matter how much the customer stretches the muscles.

Action! Evaluate The Calf

The perfect method to appraise the calf is to palpate the muscle in a relaxed position (see Fig 1. below). Begin with your patient's unaffected calf; palpate (feel) deeply between the gastroc heads supporting the knee and work down the calf into the Achilles tendon. This will give you a sensation of the deep neuro-myofascial tissue enclosing the tibial nerve, and what 'normal' feels like in this patient. Beware: it's generally quite uncomfortable to do so because of the sensitive neural structures.


Then feel the affected calf in the exact same way. If there is a difference in the deep center section (eg tightness, pain, lumpiness) and if, when you press, then it replicates their usual 'pain' or 'tightness', it might indicate a nerve tethering problem that needs hands-on intervention.

Assess the nerves of the lower limb by using the slump test (see Fig 2, below) or the straight leg raise test to cross-check your client's neural system and compare sides.

Treat The Neural Calf Complex

Once you've found something asymmetrical, you can treat the problem.

Warning: this therapy could be painful, but in my experience you need to treat very firmly to get results. Warn your patient.

Action! -- Friction The Deep Structures

In the exact same position (see Fig 3, below), ensure finger tips are together and palpating right on the tight, painful area. With firm pressure, friction across the line of the nerve with your finger tips going into the left with both hands and then to the right (firm treatment is essential).


Repeat this along the length of the tibial nerve down the area where the patient has identified a difference in the feel compared to the other side. After you have loosened the neuro-myo-fascial constructions, get your client to walk or jog to see how it feels.

Action! Educate Your Client To Self-Treat

Sitting with knees bent, they should use their thumbs to palpate; ensure they can replicate the sensation you produced with your treatment. This way, your active patient can make chronically tight and painful calves a thing of the past.
