Itching in the thigh muscles may be related to excessive activity, allergies, osteoporosis, neurodermatitis, and other reasons. It is necessary to promptly seek diagnosis and effective treatment at a formal hospital. Here are some possible causes and corresponding treatment methods:

1. Excessive Activity

If intense activities are frequently performed in daily life, it may lead to excessive fatigue of the thigh muscles. The increase of lactic acid may trigger itching symptoms. As the condition worsens, symptoms such as swelling and pain may also appear. Improvement can be achieved through massage and tuina treatment under the guidance of a doctor, which can promote the breakdown of lactic acid and reduce muscle strain.

2. Allergies

If patients frequently consume foods that easily cause allergies, such as mangoes and pineapples, it may trigger allergic reactions, resulting in symptoms of body itching. Additionally, it may lead to the appearance of erythema, papules, and other symptoms on the thighs. Improvement can be achieved by taking anti-allergy medications such as Loratadine Tablets, Cetirizine Dihydrochloride Tablets, and Ebastine Tablets under the guidance of a doctor. It is also necessary to avoid consuming foods that easily cause allergies.

3. Osteoporosis

As age increases or dietary habits are poor, it may lead to a deficiency of calcium in the body. Calcium deficiency can cause a decrease in bone density, resulting in symptoms such as itching and bone pain. Improvement can be achieved by taking calcium supplements such as Lactic Calcium Granules, Calcium Carbonate Tablets, and Calcium Gluconate Oral Solution under the guidance of a doctor. Regular physical activity can also help enhance the strength of bones and muscles.

4. Neurodermatitis

Neurodermatitis can be induced by various factors such as mental stimulation and chronic friction, which may lead to severe symptoms of body itching that may spread to the scalp, trunk, and other areas. Improvement can be achieved by applying topical medications such as Mometasone Furoate Cream, Halometasone Cream, and Dexamethasone Acetate Cream under the guidance of a doctor. It is important to prevent the symptoms from worsening after applying the medication.

In addition, it may also be related to neuropathy, which may manifest as sensory abnormalities, numbness of limbs, and other symptoms. Improvement can be achieved by taking medications such as Mecobalamin Tablets, Oryzanol Tablets, and Vitamin B1 Tablets under the guidance of a doctor to nourish the nerves and prevent continuous nerve stimulation.

It is essential to maintain proper skin care, avoid scratching excessively during itching attacks to prevent skin mucosa erosion. Regular follow-up is also necessary to monitor the recovery of the body.
