### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
Have had recurring shingles for 30 years affecting my sciatic on left side. Break outs are confined to the area at the top of the buttock periodically traveling in an arch across left buttock to the bottom of the left buttock. Recently I have had breakouts on the right side as well. 1 week ago I was putting lotion on my right leg when I felt like I had been electrocuted. I discovered a knot, about the size of a grape just above the ankle. Now there s also, on the back of my lower legs, a feeling of electricity if I even barely touch the area. There is a hardened rope feel on the back of legs. Also having the same feeling running from my neck down to my arms. Not going to lie, I m really freaking out.

### output:

Shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications. You also have problem with sciatic nerve due to the infection, so I suggest taking proper treatment with your doctor advice on medication and also take physiotherapy treatment for further relief. You can also use cold pack in painful area and the nodules at your ankle level. But if these nodules are increasing in size and no then I suggest visiting a dermatologist doctor for further check up and examination. And do the needed treatment. Here you may need to go for surgical excision and management along with biopsy if it is not getting all right. I have given here generalize guideline, and I am sure this will be helpful for patient. But in emergency I suggest visiting a doctor if needed and do what is necessary. Take care.
