If you notice pain, tenderness, and stiffness around your joints, you may be dealing with tendonitis. This condition causes irritation and discomfort in the tendons, making everyday movements difficult. You may wonder, “Does tendonitis cause swelling?’ The answer is that tendonitis can cause swelling, hindering your movement.
ANF Therapy®️ is the newest and most advanced treatment option for swelling and tendonitis. It uses small circular frequency-charged ANF Devices. This therapy aims to treat various pathologies by activating your body’s own healing process instead of masking the symptoms.
Let’s explore how tendonitis causes swelling and how to treat it with frequency therapy.
What is tendonitis?
Tendonitis is an inflammatory condition affecting tendons, the strong fibrous structures that attach muscles to bones. This usually occurs due to overuse or repetitive activities, resulting in pain and limited mobility. While tendonitis can occur in any region of the body, the most commonly affected areas are the shoulders, knees, elbows, wrists, and heels.
Symptoms of tendonitis
People with tendonitis often experience:
- Sharp pain, which worsens with movement
- Stiffness and tenderness near the affected area
- Reduced range of motion
- Swelling
- Warmth and redness

Does tendonitis cause swelling?
Yes, swelling is a common symptom associated with tendonitis. According to research, this swelling is often caused by the activation of inflammation processes following tendon injury or irritation. This response is generated to repair the damaged tissue and releases inflammatory chemicals, including cytokines. As a result, the blood vessels in the affected region dilate, which causes higher blood flow and fluid accumulation. This, in turn, leads to swelling and tenderness around the affected area.
Why tendonitis causes swelling?
When you get a tendon injury, your immune system quickly initiates the healing process. This process usually occurs in three phases:
- Inflammatory
- Proliferative
- Remodeling
Swelling mainly occurs in the first stage, the inflammatory phase. This phase usually lasts for three to seven days. At this stage, immune cells such as monocytes and macrophages migrate to the injured tendon, which releases pro-inflammatory cytokines like TNF-alpha, IL-1beta, and vascular endothelial growth factor (VEGF). These molecules can dilate the blood vessels and increase blood flow, which leads to fluid accumulation and swelling around the affected region.
In addition, the activation of platelets and the formation of granulation tissues can also contribute to this response by allowing more cells and proteins to infiltrate the injured region. If this inflammatory response is prolonged, it can lead to chronic tendonitis.
An imbalance between pro-inflammatory and anti-inflammatory cytokines is also one of the reasons for swelling in tendonitis. Increased expression of TNG-alpha, IL-1beta, and cyclooxygenase-2 (COX-2) is also associated with prolonged inflammation, which can delay tendon healing and cause swelling.
Moreover, sedentary people with lower mechanical load on tendons have higher levels of inflammatory markers, which can lead to increased matrix metalloproteinase (MMP) activity. MMPs, especially MMP-2, MMP-9, and MMP-13, can degrade collagen, delay healing, and maintain low-grade inflammation. This state can cause persistent swelling and increase the risk of tendon degeneration.
In the case of chronic tendonitis, swelling may persist due to neurogenic inflammation, where nerve fibres grow into the tendon and release neuropeptides such as substance P and calcitonin gene-related peptide (CGRP). These molecules further increase vascular permeability, which can worsen fluid accumulation and swelling.
How to Stop Swelling Caused by Tendonitis?
ANF Therapy®️ (Amino Neuro Frequency Therapy) is an advanced treatment for swelling caused by tendonitis. It is a drug- and chemical-free therapy based on Einstein’s concept of frequency medicine.
This therapy utilises frequency-charged, small, circular ANF Devices. These devices are applied to specific areas of your body and aim to reduce inflammation, support tissue healing, and optimise neural communication. ANF Therapy®️ is designed to create a balanced environment in your nervous system and activate your body’s natural healing process.
How ANF Therapy®️ Works for Tendonitis Swelling
This treatment involves the following steps:
History
Your ANF Therapist will take a detailed history to assess the severity of swelling, pain, mobility limitations, past treatments, and overall health conditions.
Physical Examination
During the examination, your therapist will assess muscle tension, inflammation, nerve sensitivity, posture, and range of motion to determine the impact of tendonitis.

Application of ANF Devices
After evaluating your condition, your ANF Therapist will apply specific ANF Devices to your body. These devices include positive and negative anti-inflammatory Devices, antioxidant Devices, energy Devices, and Nitric oxide Devices, each meant to activate different healing responses. Hydration is crucial for optimal results. You should drink at least 1-2 glasses of water per hour to support the detoxification process and facilitate recovery.
Expected Outcome
According to Dr. Mikel H-G Hoff, the founder of ANF Therapy®️, most patients experience noticeable swelling and pain reduction within the first session, often achieving around 50% improvement. However, individual responses vary based on the severity of the condition.
Follow-Up
Your ANF Therapist will schedule follow-ups to track progress, adjust the treatment plan, and guide you about lifestyle modification. They will change ANF Devices every 72 hours for optimal healing. The recovery time for tendonitis varies but typically takes several weeks, depending on the severity of the inflammation and tendon damage.
