The clot is likely a small bruise (haematoma) or a minor superficial blood clot, which is common after a needle puncture. It is usually harmless and often resolves on its own. Apply a warm compress instead of ice and gently massage the area to improve circulation. You can also use a topical heparin gel, such as Thrombophob Gel, to reduce swelling and help prevent clots. If the area becomes very painful, red, swollen, or warm, consult a doctor immediately.

Your father-in-law is likely experiencing a stroke caused by a brain blood clot, resulting in right-sided paralysis. You should seek a second opinion from a neurologist or stroke specialist and bring all medical records, including CT/MRI scans, lab reports, and a list of his current medications. Early rehabilitation, such as physiotherapy and occupational therapy, along with managing risk factors like smoking, is important for recovery and preventing further complications.

Thrombophob Gel, which contains Heparin (a blood thinner) and Benzyl nicotinate (a vasodilator), is generally safe for treating small, superficial blood clots (superficial thrombophlebitis). It helps reduce inflammation and prevents the clot from enlarging. Apply a thin layer to the affected area 2-3 times a day and gently massage it. However, please consult a doctor before use to ensure it is appropriate for your condition. If the clot worsens, spreads, or you notice increased swelling, redness, or pain, seek urgent medical attention.

Persistent pain and swelling after 12 days may indicate superficial thrombophlebitis (inflammation of a vein near the skin's surface) or an infection. You should see a doctor promptly for an examination. Meanwhile, stop using Thrombophob Gel and apply warm, moist compresses to the affected area for 15?20 minutes to improve blood flow and healing. Keep the affected arm elevated while resting.

A heart attack is a medical emergency and cannot be treated safely at home. Call emergency services immediately (e.g., 108 in India). While waiting for help, chew one 325 mg aspirin if you are not allergic, to help prevent further blood clots. Stay calm, rest, and avoid any physical activity to reduce strain on your heart.

Redness, pain, and swelling at the injection site may be due to infection, severe inflammation, or a reaction to the injection. You should contact your doctor immediately for evaluation and possible treatment. Meanwhile, you can apply a cold compress for temporary relief, but do not massage the area until a doctor examines it.
