Rheumatic and gouty symptoms well marked. Worse before a storm is a true guiding symptom especially a thunderstorm; after the storm breaks the patient feels better. The aggravation before the thunderstorm does not at all seem to depend on the coldness or dampness, but partially at least on the electric conditions of the atmosphere. This is like Phosphorus, Natrum carb, and silicea. Rhododendron resembles Rhustox, in that it is worse during rest but better during motion. Again the pains of Rhododendron, which are aggravated in damp weather, differ from those Rhustox, in that they seem to be seated deeper and are felt in the periosteum, as in the teeth, and in the bones of the forearm and tibia. These pains are not, to make it difficult to choose between these remedies. Acute inflammatory swelling of joints, wandering from one joint to another; severe at night; < in rest and during rough stormy weather. Joints swollen, Gouty inflammation of great toe-joint. Rheumatic tearing in all limbs, especially right side; worst at rest and in stormy weather. Stiffness of neck. Pain in shoulders, arms, wrists; worse when at rest. Pains in bones in spots, and reappear by change of weather. Cannot sleep unless legs are crossed.
