Make sure your calcium increased along with the Vitamin D ... mild calcium deficits can cause muscle pain.

Have you tried other NSAIDs, such as Sulindac?

Post-partum joint pain seems to be common, based on the number of google results I got. Some of the sane suggestions (ignoring the quackery, essential oils, and the like) were to establish a mild regular stretching and warmup regimen, increase your intake of oily fishes (there's some evidence it helps non-rheumatic joint pain), and wearing leggings and wrist warmers to encourage better circulation.

Have yourself checked for MS. Some women with the remittent type develop pains during and after pregnancy. My SIL developed it with her first pregnancy and it became worse as she had more children. A spinal tap is the normal test to rule it out. There are blood tests but for definite proof.

My daughter has the exact same thing although no pregnancy.They checked her heart,kidneys r arthritis,autoimmune illness.Hers started with big toe,feet,knees,back.she can hardly get around.

When you are pregnant you are supplying nutriments for two people and your body will make sure the baby get first choice. So that is why they recommend prenatal vitamins. After the baby is borne it would be very easily a mineral or vitamin deficiency problem. Doctor bless there sole know lots about drug but nothing about nutrition. Asking them about a vitamin or mineral deficiency is like asking a gardener about rocket science.

The same thing happened to me when I was 38. I was at a point where I couldn't walk down the stairs anymore, lift anything with one hand, open a door with one hand, etc. My skin felt like I had the flu, any light touches, movement of arm hair was very uncomfortable, almost painful. I do have autoimmune conditions and was dealing with a rheumatologist and was taking medications for it. They are very strong and you need monthly testing to be sure your liver can handle it. I also started reacting to them. I went the natural route and it is the best thing I ever did! It is a lot of work and constant searching to figure your own body out. I have been off medications for three years now and have only taken a couple of Aleve's or Tylenol when I get off course. Look up elimination diets (the stricter the better) and see how you feel a solid ten days into it. I went into this not believing but was desperate. I haven't looked back since! It takes a long time to get fully recovered. It took me almost six months before I could make a full tight fist again. It took me two years to be able to get my rings off. I actually gained weight and this is not due to losing weight as I was pretty thin before. I still see benefits as time passes. Yeah, I was in rough shape. Definitely write down everything you eat, how you feel, learn your micronutrients, about antinutrients, hormones, etc. There is so much out there to help you out. My last child was the worst, it started hitting me at 5 months post partum.

Thanks everyone for all the great feedback! I'm surprised that anyone responded let-alone so many great comments - very enheartening! A couple of responses...

Calcium levels ok. Stretching/yoga helps certainly (hard to find time with work and small children but I do do it). Even though I'm careful, my muscles almost react in reverse by knotting up like crazy. They ache badly for days after but I still try to do light stretches throughout the day. If I'm careful, more gain than pain. Haven't tried Suldinac; will ck into it.
I did wonder about MS too. I think it was dismissed early on but am going to ask again.
Went to a naturopath doctor and tried what he prescribed but I've felt no difference. Disappointing.
Firm believer in what you eat makes a difference. Haven't tried any kind of elimination diet though. Right now, I just don't have it in me. Someone asked about fatigue - extreme fatigue! Half of that is because my kids don't let me sleep. I've been sleep deprived for years, not exaggerating. Definitely makes it worse.
Doctor wants to put me on methotrexate but am nervous about the side effects. If I was confirmed to have arthritis (have no joint deformities so he can't decide either way) might be more comfortable taking it but would like to know what is going on first.
Not lupus; RA factor and 2 other inflammatory markers were all high. Would like to see more specialists but just wants me to take the drug and if that works then they can dismiss me I guess. Will keep pushing for answers though but up against a wall.
Thank you again! I will post again when I have an update.

I'm sorry you're going through all this. I've had a lot of health issues since I was in my mid 20s so I know how tough it is. I'm almost 60 so I've dealt with this for over half my life.

One thing I have and I think it's more common than people think is low magnesium levels. Doctors don't recognize this as they only check blood serum magnesium levels that will always be high as the body pulls magnesium from the bones to keep the blood levels up so you don't have a heart attack. Instead, they need to check the cellular magnesium level to diagnose low magnesium.

There are over 300 functions magnesium is needed for in the body including relaxing muscles and removing lactic acid from them.

Here are a couple of articles on the role of magnesium in health:

I don't know if this applies to you, but a lot of pain that doctors fail to diagnose is myofascial pain where the muscles/fascia get knots in them that refer pain elsewhere. I've had severe myofascial pain since I was 15 years old, and had every sort of pain in almost every part of my body that couldn't be diagnosed. Fortunately I stumbled on a book on the subject years ago, and have been able to control my pain doing trigger point massage. Everyone has myofascial pain from time to time. Check out triggerpointbook.com. This book and my two-headed percussion massager has made my life manageable.
