### output:

Hi, welcome to our site. I am Chat Doctor, MD. Read your query. That is a very significant question and I appreciate your problem. I will try my best to answer your Quertle pain you described seems more appropriately localized to the back, not the skin. The backache with sharp shooting pain radiating to the skin is a typical feature of nerve damage to the back. In this relation, I will therefore suggest testing an MRI of the spine. Reason being it's a more detailed study than a normal x-ray, and unlike the x-ray, does not tell us about the nerves. Also, a nerve conduction velocity (NCV) may be done if the skin affected is over the upper/lower limb. This further tells us about the location of the pain. If found affected, we may add a medicine like Gabapentin/pregabalin, and you may need to undergo physiotherapy. In case you are concerned about your skin, please let us know if there are changes in skin, like the texture and the color of the skin. We may be able to consider the information with pictures and let you know more about it. I hope this helps you. Inform the reports mentioned above/if any other, so I can be of help further. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)Best of luck. Chat Doctor.
