Why Is My Type Turning Black Blue After Getting A Cortisone Shot?
Necrosis of the toe most likely
Detailed Answer:
Hello,
Bluish-black discoloration of the toe is concerning for tissue necrosis, which is the death of tissues caused by reduced blood flow. Cortisone injections have known to cause such necrosis. However, since you had only one cortisone shot and that too 10 months ago, it is an unlikely cause.
Any factors that affect blood flow like atherosclerosis, compression of arteries etc can lead to such symptoms. Whatever the underlying cause, tissue necrosis is warranted immediate medical attention.
Depending on the extent of necrosis further treatment ranging from use of antibiotics alone to debridement to surgery will be needed.
So, please be advised to follow up with the emergency room as soon as possible.
Hope this answers your question
Please let me know if you need further clarification.
