Changes in mood and behaviour - some people actually feel better in themselves when they take steroids. However, steroids may aggravate depression and other mental health problems and they may occasionally cause mental health problems. If this side-effect occurs, it tends to happen within a few weeks of starting treatment and is more likely with higher doses. Some people even become confused, and irritable; they may even develop delusions and suicidal thoughts. These mental health effects can also occur when steroid treatment is being withdrawn. Seek medical advice if worrying mood or behavioural changes occur.
This may be considered in very difficult cases. Surgery is usually only advised if your pain has not eased after 12 months despite other treatments. The operation involves separating your plantar fascia from where it connects to the bone; this is called a plantar fascia release. It may also involve removal of a spur on the heel bone (calcaneum) if one is present. Surgery is not always successful. It can cause complications in some people so it should be considered as a last resort. Complications may include infection, increased pain, injury to nearby nerves, or rupture of the plantar fascia.
