Yesterday I had a tooth extracted and last night began to get a skin rash over different parts of my body. I was taking clindamycin prior to the surgery and after completing the 7 day prescription stopped it two days before the surgery. What is causing this skin rash? I have had shingles but I am worried about this

I am taking oral benadryl for the itching which has helped. The rash is on my elbows, my lower back and my upper thighs. There is no pain at the rash sites. I have had previous problems with a rash on my elbows for which my dermatologist prescribed a topical cortisone medication. I am unable to send you any pictures as I am alone in my home and have no experience doing that. I would not say that the itching is continuous but moderate, more of a nuisance but again I have so far taken 50mg of benadryl six hours apart since last night. That would be three doses so far. I am not sure if I should continue taking it. Thank you.

Brief Answer: The condition is simple urticaria Detailed Answer: Hello, Welcome again to the forum and thanks for posting important details. After reading the complete query I can make out that your problem is not at all herpes zoster or shingles. The condition is simple acute urticaria or also known as hives. To tell you Medically - Our blood contains multiple type cells including red blood cells and white blood cells. Specifically these white blood cells provide immunity to our body which are of further multiple types. Whenever anything in body is not suitable or offending to body then the number of white blood cells increases transiently. Particularly these cells which increase are eosinophils and basophils which are also known as mast cells. These cells contain granules which have a specific chemical known as histamine. So as soon as any offending factors come in contact there is bursting of the mast cells. There fore this histamine is released and we experience variable degree of itching and the kind of rashes which occurred in yourself. The rash can remain for a very transient period to upto multiple hours. It can remain for more than 12 hours too depending on the intensity of the offending factor but never more than 24 hours. Now the type of offending factor are innumerable including our food, environmental factors including temperature variation, heat, humidity, cold, dust and even simple of fragrances in air and multiple of other related things. For the treatment part - it is quite simple and treated with drugs which inhibits the histamine release also known as Antihistamines. Benadryl is a good drug and can be taken for up to 4 times a day. The only problem is sedation with benadryl. If you are comfortable with the sedation part then you can continue the same. In my patients I start with loratadine as it is very simple medicine without any side effects of sedation. It can be take foe 2-3 tablets/day. In general acute urticaria may remain for few day to weeks. In most of the cases as our immune system and body get adjusted to that particular offending factor so it then self subsides. You do not worry about the possibility of shingles as it occurs for only once in life and that too only at a particular one side of the body and never as generalized rash. I hope these information will help you in dealing the condition better. If you have any further queries I will be glad to help you. With good health wishes, Dr Sanjay MD - Dermatology
