Search bjsm plantar fasciitis and it will take you to a systematic review for best management. Skip down to the best practice guide for recommendations. I had suspected I currently have this but my med husband doesn’t believe it matches but gave this article a squiz last night.

To be honest I think this is really something you should visit your doctor for.
To help treat pain caused by plantar fasciitis, your doctor may suggest that you:
-take pain-relief medicine, such as ibuprofen or paracetamol
-rest your foot as much as possible
-wear shoes with good support and cushioning
-insert heel pads or arch supports (orthotics) in your shoes
-wear night splints while sleeping
-apply an icepack to your foot for 10 to 20 minutes up to 4 times daily
-They may also suggest some exercises for you to do to stretch your plantar fascia, to better absorb your body weight.
Plantar fasciitis can often last for weeks or months.
If these measures don’t work, your doctor may give you steroid injections in your heel suggest surgery. These treatments are rare and usually only used in the most severe cases.

The best recommendation is stretching your foot and taping it up. A massage can help, heat rubs. After 4-6 weeks if there’s no change to look into orthotics. Look at your rest-activity balance, maybe some more exercise and movement is needed. A GP will be able to assist further, if you need smaller heels or different shoes depending on the location. Hoping you can find a resolution.
