Lumigan Eye Drops are primarily used to treat high pressure inside the eye, such as in glaucoma or ocular hypertension. They help reduce intraocular pressure to prevent damage to the optic nerve.

Regarding your father's symptoms of swelling and severe pain in his fingers and shoulders, these are not conditions treated with Lumigan Eye Drops. These symptoms may indicate an inflammatory or rheumatologic condition that requires evaluation by a doctor.

It is important that your father sees a doctor, preferably a rheumatologist or general physician, for a proper diagnosis and appropriate treatment. Self-medicating with eye drops meant for glaucoma will not address his symptoms and could delay necessary care.

If you need help with managing his pain and swelling, please consult a doctor who can prescribe the right medications and investigations based on his condition.
