Hi,
Darkening or discoloration of the upper thighs can be caused by various factors, including medications, poor circulation, and skin conditions.
Blood pressure medication can sometimes cause changes in the skin, including discoloration or darkening, as a side effect. However, it is important to rule out other possible causes as well. Poor circulation can cause the skin on the upper thighs to appear darker, and certain skin conditions, such as
eczema or
psoriasis, can also cause discoloration.
If you have been walking for extended periods, it is possible that the discoloration could be due to the increased pressure on the thighs. This type of discoloration is usually temporary and should resolve on its own.
If the discoloration persists or is accompanied by other symptoms, such as pain, swelling, or itching, it is important to see a doctor for further evaluation. Your doctor may perform a physical examination and run tests to rule out any underlying medical conditions. Depending on the cause of the discoloration, treatment options may include topical medications, lifestyle changes, or adjustments to your medication regimen.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
