The fact that your pain has already reduced after 25 days of treatment is actually a positive sign. Nerves usually take much longer to recover than pain, so mild numbness can persist for weeks or even months.
An epidural steroid injection is not compulsory.
It is generally considered if:
Pain remains severe despite 6-8 weeks of medicines and physiotherapy.
Pain is so severe that walking and sleeping become difficult.
Surgery is not required but pain control is needed.
It is not a permanent treatment. It mainly reduces inflammation around the nerve so that rehabilitation becomes easier.
If your pain is gradually improving, I would usually continue conservative treatment before deciding on an injection, unless your spine specialist finds a strong indication.
In Ayurveda, this condition is commonly understood as Katigraha/Katishoola with aggravated Vata affecting the lumbar region and sciatic nerve (Gridhrasi).
And I can guide you properly only when I get a chance to have an online consultation so I would recommend you to consult online so that I can provide you with detailed treatment.
Next Steps
My advice would be not to rush into an epidural injection if your symptoms are steadily improving and
Get online consultation.
Most people with disc bulges improve without surgery. Recovery often takes 6-12 weeks, and numbness may take longer to resolve than pain.
