A painful, burning sensation on the outer side of the thigh may mean that one of the large sensory nerves to your legs--the lateral femoral cutaneous nerve (LFCN)--is being compressed.

These grafted cacti -- occurring in yellow and white as well as red -- typically live only a few years and do not grow appreciably. The Gymnocalycium cultivar -- sometimes called ruby ball cactus or moon cactus -- is actually two cacti in one.A pure red cactus seedling lacks the ability to produce chlorophyll and will die unless it is grafted onto a green one.The green feeds its mutant mate sugar molecules produced from water and carbon dioxide.he Gymnocalycium cultivar -- sometimes called ruby ball cactus or moon cactus -- is actually two cacti in one.
The moon cactus (Gymnocalycium mihanovichii var. friedrichii or Hibotan) is prized for its colors. The plant is without chlorophyll, which means that instead of having a green body, it appears red, orange or pink.This also means it can't produce food, so to survive, it must be grafted onto the stem of another cactus.acterial infections or other fungal infections may also be causing the stem of your moon cactus to turn brown. In general, if the brown part is soft and mushy, and it covers most of the stem, your plant is probably beyond saving. Your best bet is to discard it and start over with a new, healthy plant.
