<s>[INST] hi I had ankle fusion 1 month ago . since then it feels like someone drop a hot coal on my foot and like its a sever burn now yesterday the incision started feeling this way. I figure it nevre damage, or them healing pain meds don t help. is this normal and how long does it last [/INST] Yes it seems that small sensory nerves would be damaged but they could be due to your initial problem that led to ankle fusion, your diabetes status needs to be evaluated and other causes of peripheral neuritis needs to be ruled out. You need x ray and blood investigations to rule out infection. </s>
