Well as you describe,possible causes may include Heel spurs,Plantar fasciitis,retrocalcaneal bursitis,gout.
You should avoid orthotics for a while as your pain is getting worse.
Take OTC Motrin.
Also do gentle massage with muscle relaxant ointment on affected area.
Physical therapy can be helpful.
You should see a podiatrist in person for a clinical examination and further MRI/X-ray can be done to rule out underlying possible cause.
Your doctor may advise you perfect orthotics for a particular pain.
Night splint can be advised.
Extracorporeal shock wave therapy and steroid injections can be given.
