Top 5 Pain in the Thumb Side of the Forearm Causes

  1. 1.Thumb Arthritis

    Arthritis of the thumb is common with aging and occurs when cartilage wears away from the ends of bones that form the thumb joint. This can cause severe pain, swelling and decreased strength and range of motion, making it difficult to do simple tasks, such as turning doorknobs and opening jars.

    You should visit your primary care physician to confirm the diagnosis and discuss treatment options for managing symptoms.

    Rarity:
    Rare
    Top Symptoms:
    thumb pain from overuse, difficulty moving the thumb, pain in the thumb side of the hand, spontaneous thumb pain, thumb pain that affects sleep
    Urgency:
    Primary care doctor
  2. 2.Chronic Nail Infection (Paronychia)

    Chronic Fingernail Infection (Paronychia) is caused by repeated damage to the cuticle (the thin layer of skin that covers the base of the nail). The cuticle protects the nail from infection, and when it's damaged again-and-again, it can predispose someone to infections of the nail (paronychia).

    You can treat this at home with a number of changes - 1) moisturizing with lotion, 2) protecting your hands from water by using light cotton gloves under heavier-duty vinyl gloves, 3) avoiding any nail polish/remover/hardener/conditioner, 4) using mild soaps to wash your hands and drying them completely and carefully, 5) using a topical steroid to promote healing

    Rarity:
    Rare
    Top Symptoms:
    spontaneous finger pain, fingernail pain, cuticle loss, fingernail swelling
    Urgency:
    Phone call or in-person visit

  3. 3.Carpal Tunnel Syndrome

    The carpal tunnel is a narrow passageway filled with ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually, and as they worsen, grasping objects can become difficult.

    Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor will diagnose carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines. If symptoms do not improve with these less invasive treatments, your physician may recommend surgery.

    Rarity:
    Common
    Top Symptoms:
    spontaneous shoulder pain, hand weakness, wrist pain, pain in one hand, weakness in one hand
    Urgency:
    Primary care doctor
  4. 4.Ulnar Nerve Entrapment of Elbow

    Ulnar Nerve Entrapment of Elbow is the compression of the ulnar nerve, causing numbness and/or weakness in the hands.

    You should visit your primary care physician. Diagnosis is made by looking at your symptoms and confirmed with a test of the nerves. Treatment depends on severity. If no weakness, splinting and physical therapy. If weakness, surgery to decompress the nerve.

    Rarity:
    Common
    Top Symptoms:
    hand weakness, pain in one hand, numbness in one hand, weakness in one hand, pain in one elbow
    Urgency:

  5. 5.Bruised Hand

    A bruise occurs when small blood vessels break and leak their contents into the soft tissue beneath the skin, which causes the purple color of the bruise.

    You do not need treatment. It looks like a simple, uncomplicated bruise, which should heal on it's own in the next few days.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one hand, hand pain from an injury, hand injury, swelling of one hand, palm bruise
