What is the blister like formation on my ankle?

Question

Hello doctor,

I am a 50 year old male. I am attaching a picture of blister like formation on my right ankle, which is very old one and is present without any pain. Now, I am feeling some uneasiness while wearing shoes though still there is no pain. Is it of a sincere concern that needs to be taken care of immediately? I did not mind it until my elder sister started insisting me to investigate the matter in recent past. It is also to note that the size has recently been increased very slightly since its formation probably 20 years back. Please advise and remove my anxiety.

Hi,

Welcome to icliniq.com. I have gone through the pictures (attachment removed to protect patient identity). It appears to be a ganglion. These are usually benign. The indication for surgical removal is pain, interruption in your daily activities, infection and rapid growth. It seems that your ganglion is growing very slowly. If is not causing any numbness, pins and needles in your foot or has not been infected or causing severe pain, then you can just observe it. It may actually reduce over time. You can take Diclofenac sodium 25 mg one or two pills twice daily for pain, if you have no kidney problems.
