Hi,
Thanks four your query.
Degenerative
disc disease in you causing two problems. One is back pain and other is tingling and numbness in leg. I also agree with you that since you have undergone multiple surgeries it is difficult to go for another surgery. I have following advice for you.
1. You should not stop
physiotherapy as when you stop it your back muscles will hurt, so continue physiotherapy. You do not need therapist every time, you can understand exercise and can do it at home.
2.Lumbosacral belt is also helpful because it prevent abnormal movement of spine
3.Apart from medication you taking i will also suggest
Pregabalin and Methylcobal also so nerve pain will also be relieved.
4. If nerve pain is not improving then you can get
discectomy, if you are worried about your scar and keloid then you can opt for endoscopic discectomy.
5. All other medication you can continue to take, i would suggest
fluoxetine at the place of Amytryptalin,.
I hope these measures will help you. Let me know if you want to ask any thing else. thanks and take care.
