Widespread itching on different parts of the body may occur due to fungal infection, allergy, or skin irritation. Since you developed swelling and blisters after taking the medicines, it may have been a reaction to one of the drugs. Avoid restarting the same medicines on your own and keep the skin clean and dry. A doctor should examine your skin again to identify the exact cause and adjust the treatment.

Bleeding at 20 days of pregnancy is a warning sign and needs consultation. Stop Betnesol unless your doctor told you to continue it. The bleeding may be from the uterus or a urine infection, so please see a gynaecologist or go to a hospital for a scan and urine test. Early treatment can help protect the pregnancy.

If an insect has bitten you, just wash the area, apply an ice pack, and use calamine lotion or a mild anti-itch cream. See a doctor if the swelling increases or the area becomes very painful.

Betnesol should not be taken during pregnancy without a doctor's advice. Inform your doctor if you are pregnant or planning pregnancy before taking any medicines.

If you have stomach issues after taking Betnesol, you can take an antacid and avoid spicy foods. If the pain gets worse or does not improve, it is best to see a doctor.

Oral lichen planus can be long-lasting, and flare-ups are common. Since you are already on Dapsone, Betnesol Forte, and Tackvido Forte gel, it is important to continue regular follow-ups with your doctor to check for side effects and adjust doses. You can reduce irritation by avoiding spicy foods, very hot drinks, and stress triggers. Using a gentle mouthwash and keeping good oral hygiene also helps.
