The symptoms described in the question are characteristic of a specific remedy in homeopathy. Let's analyze the key features:
Worse from lying down, unable to lie down:** This is a strong indication for *Lachesis*.
Face purplish and puffed, eyes engorged, eyelids bloated:** This suggests a plethoric state with circulatory congestion, often associated with *Lachesis*.
Sat perfectly still with pain in the head as a surging sensation which came up the back of neck and head and then over the head:** This type of headache, with an upward surging sensation, can also point towards *Lachesis*.
Considering these symptoms together, especially the marked aggravation from lying down and the congested appearance, *Lachesis mutus* is the most probable homeopathic remedy. *Lachesis* is a polycrest remedy known for its symptoms related to circulatory disturbances, a sensation of constriction, and aggravation upon lying down or after sleep.
Let's briefly consider why the other options are less likely:
Opium: While *Opium* can be indicated for states of altered consciousness and congestion, the specific aversion to lying down and the surging headache are less characteristic.
Ars. album (Arsenicum album): *Arsenicum album* is often indicated for restlessness, anxiety, and burning pains, with a general aggravation around midnight or in the early morning. The aversion to lying down is not a primary characteristic.
Spigelia: *Spigelia* is primarily known for its action on neuralgic pains, particularly left-sided heart conditions and trigeminal neuralgia. The described symptoms do not strongly align with the typical *Spigelia* picture.
Therefore, based on the totality of symptoms, *Lachesis* is the most probable homeopathic remedy.
