Pain

I work for a man that writes a health newsletter that promotes all natural type things and he has been doing it over 25 years. He recommends lots of different combination of all natural vitamins for all kinds of different ailments. In the five years I have worked here I have never had a real need to follow any of them.
When I first started running I was getting very sore in my knees, hips and ankles. Understandable since I had and still do have a lot of weight pounding down on my joints.
I decided to follow his joint pain protocol and eventually the pain did subside. I was never sure however, if the vitamins were working or if my body had just gotten used to the running.
Ever since then I have been breaking out quite a bit on my face. Not even really acne but more like a light rash around my nose. Dry spots that were easily prone to irritation.
I knew it either had to be from the running or the supplements. Well I wasn’t about to stop running since it was doing wonders in the way of shrinking my body and lowering my blood pressure and such so I decided to go without the supplements for a couple of weeks and see if that made a difference.
It takes a few days to get the supplements out of your system and I continued to run on those few days, taking care to wash my face thoroughly after each run. Then I got sidelined by my period, car problems and my own laziness and didn’t run for four days. When I resumed this past Tuesday I ran for 30 minutes and was struck by a pain in my thigh as soon as I stopped. Throughout the rest of the day the pain traveled from my hip to my thigh to my knee and back.
That night I soaked in Epsom salts and used icy/hot and then it went away.
Wednesday I set out to walk the loop, only walking because I didn’t want to cause anything else to happen to it and was only able to walk part of it due to the pain coming back on the uphills after I attempted a power walk.
Thursday I was paranoid enough just to only take a mild stroll down to the cul de sac and back just to get some sunshine. My leg felt pretty okay with that and so today I decided I would attempt a run again since we had to be at work early again.
I stretched and started out. It was hurting a bit but I soon got into the groove and it was fine. After 30 minutes of running I stopped and headed out Starbucks to get my reward for my early morning run(tall skinny caramel latte–2 points!) and as soon as I put weight on my foot after sitting in the car the pain was there and it was intense! After three steps it was fine again. This went on all morning and now it is finally starting to ease off.
So my question is, was my supplement regimen actually working and keeping away any joint/muscle pain the whole time Ive been running or do I have something seriously wrong with my right leg?
I don’t have an answer obviously but I started taking the vitamin protocol again today and will continue to see if it helps. I can deal with bad skin but Ill be danged if I’m going to stop running!
My other theory is that I have a pinched nerve in my back.
I had one once, years ago when I was at my heaviest. We had just spent a week in England I can only assume I got it from falling asleep in a sitting position on the plane for a long amount of time. The symptoms are kind of similar in the way that the pain happens as soon as I try to put weight on that leg after sitting for an extended period of time and then it goes away as I start walking. I don’t remember it traveling to other locations though. It was very painful but it was usually located to one spot on my leg. I also remember getting a numbness in that area for a couple of days before the pain started and I don’t recall that happening this time around. I DO remember getting a fluttering sensation in my hip/inner thigh area for a couple of days before this started though, not sure if it is related.
Back then my doctor gave me some stretching exercises and told me it would work itself out, and eventually it did.
The problem I have with that is my I have 2 10 Ks next month and I want to be 100% for both of them. I also don’t want to do any more damage by running through the pain. Ug. I’m just at odds right now.

I guess all I can do is take my supplements and see if it makes a difference. If it doesn’t I guess a trip to the chiropractor is in order. Pffffftt

Edited to add: The pain is now mostly in my knee.  Please comment if you have any advice or suggestions or are familiar with this sort of thing at all.  Thanks!!!!!!!!
