Well last year my Dad got L5/S1 sciatica from herniating his disc from lifting a large pot plant awkwardly. He suffered terribly and thought he would lode the house as he is a painter/decorator and needs to be able to move. He took Panadol Osteo and other painkillers when needed to try and kerb the intense nerve pain. Exercises helped, and so did acupuncture to a certain degree. One thing to note about sciatica is to avoid being inactive and to stay as active as you can. (or at least in my Dad's case this was true)The pain slowly decreased, but then plateaued from 9/10 intense pain to 5 or 6/10 pain.
I am writing this post to try and help anybody, anywhere, who may have the same condition as I know how bad it can be after watching my Dad go through with sciatica.
Anyway, my Dad was introduced to capsaicin cream by a pharmacist when he told her about his condition. As far as I am aware, capsaicin cream is usually used for other nerve pain but it has worked very well for my father. What it does is it dampens the signal that is received by the surrounding nerves, thus reducing the pain signal from the nerve that is received by the brain.
Capsaicin cream is taken externally and applied to the problem area. It burns hot on the skin, but this burning sensation reduces with regular use. (Capsaicin is what makes chillies hot) The improvement was gradual for my dad, but it kept improving and today I no longer hear him mention anything to do with sciatica. So this cream does not work straight away, but rather with regular use.
As I said before, I really hope that I can help someone in a similar situation. As my Dad found out, what works for others may not work the same for him, like the acupuncture (which did have an effect, but not consistent or significant enough for him).
He found forums on the internet about many other people around the world in the same position, with one poor person considering suicide. I really hope this can help. Best of luck to all of you out there.
