Hi welcome to HCMForum. It is not clear weather you have consulted a doctor or not. It appears to be concerned with the nerve neuritis
pressure or injury
of ulnar nerve
. I advise you to consult an orthopedic surgeon for diagnosis and treatment. you may need to go for MRI
Besides i advise you to follow some diet recomendations as Dont take potato other tubers tomato caulli flower coconut egg chicken and sea fish as they will acclerate the pain receptors. wishing for a quick recovery. thanks for calling.
