Hello Doctor B I strained my back a few days ago and probably have a herniated disk. Initially I felt excruciating pain in my back and my left buttock and I couldn't stand up straight anymore. This went away after 2 days but then I felt pain down my left leg, all the way down into my foot. Now the back-pain has stopped and the pain in my leg as well. But I still have a little bit of tingeling and a slight numb sensation at the back of my foot (sole) and the left side of the foot. I can walk on my heels and I can tiptoe, but walking on my toes is more difficult with my left foot, but no other sensations out of the ordinary are there. I suppose all of this may be caused by the prolapsed disk pushing against the sciatic nerve. What remedy could I take to cure this? Is surgery necessary?

I don't think surgery is at all necessary. Some good medicine, rest and physiotherapy should be suffecient. The symptoms you have suggested indicate a medicine like Kalmia. But they are very local symptoms. If your constitution, causative factors, modalities etc are taken into account, a different medicine may come up. If you can find a local homeopath, please pay him/her a visit. And take this remedy suggestion with you. Also you should get in touch with some physiotherapist.

Wishing you health,
Dr. B
