Hi, The discoloration that you are experiencing at the site of the injection may be a side effect of the cortisone injections. Cortisone is a type of steroid that is commonly used to treat alopecia and other inflammatory conditions. However, cortisone injections can sometimes cause skin discoloration, particularly in people with darker skin. The discoloration may be due to a decrease in the production of melanin, which gives skin its color. This can result in a loss of pigmentation, which may appear as a white patch. In some cases, the discoloration may be temporary and may go away on its own. However, in other cases, it may be permanent. If you are experiencing discoloration at the site of the injection, it is important to talk to your doctor about your concerns. They may be able to recommend a treatment to help reduce the discoloration or refer you to a dermatologist for further evaluation. In some cases, topical creams or ointments may be used to help restore the skin s color. Other treatment options may include laser therapy or micro-needling. However, it is important to note that these treatments may not be effective for everyone and may have side effects of their own. It is also important to note that cortisone injections can have other side effects, such as thinning of the skin or the development of stretch marks. If you are experiencing any unusual side effects or are concerned about the risks associated with cortisone injections, be sure to discuss your concerns with your doctor. Take care.
