Osteoarthritis in the right knee

Hi, I would really appreciate some help.

I have osteoarthritis in my knees, specifically the right knee. I am finding it very difficult to climb and descend stairs, and walk down slopes. I have been prescribed diclofenics and paracetamol, but I do not want to take them.
I had posted this before and answered many question from a homeopath who is now suspended, so I have to start all over again.

Info on remedies already taken, prescribed by homeopath online but not here in this forum:

April 2017 Nat Mur 1m , 2 pills in half litre spring water, shake and drink over the day. next 6 days, refill bottle, no more pills, shake and drink. Result: no change, so another week of the same was prescribed. No change to knee, but I did have reactions: lots of phlegm, severe cramping in left leg, hot flushes (I have never had them before), teeth sensitive, and diarrhoea.

1st June Sepia 1M in water as before. Result: No change to knee but tiredness in the morning worse, more phlegm, breathing difficult uphill and talking, feel as if getting or finishing a cold, and feel very intolerant, irritable and swearing more!

14th June Sulpher 30ch. Knee slightly better. Waited a short while, then as knee worsened, took remedy again for a week, this time in water. Pain shifted from under the knee to around the knee cap more.

30th August Ruta Graveolens 30c twice daily for up to 7 days. Also recommended cranial osteopathy. Ruta made no apparent difference. Cranial Osteopath said that Psoas muscle on right side is too tight, causing the femur to pull in too much, so the foot tries to rebalance by twisting the tibia out. I am continuing the osteopathic treatment, and also have purchased new orthotic insoles.

22nd October Rhus Tox 30c , one daily for a week. No change. The homeopath seemed to feel there was little point in prescribing more whilst I am receiving the osteopathic treatment.

Then in February 2018 I messaged this forum, and was prescribed syphilinum 1M .. 4 drops One dose only. Once a life only. No more no repeat. In a New separate disposable glass with some water in it. This had little effect, apart from dreams very vivid, though not unpleasant and very tired in the morning.

I was then given Silicea 30c . 2 pellets twice a day for 3-4 days.
This I have just done. I only managed 3 of the 4 days as it has had an affect: my lower back really aches, knee is more painful, soles of feet sore when walking, dry phlegm in back of throat, difficult to get rid of, voice hoarse, and very very tired for most of the day.

Apologies for such a long post......
