Well first off. . sorry for your aches and pains. Fibromyalgia can be mistaken for many different kinds of things. Having had previous injuries you could just be suffering from the repercussions of other injuries. Being diagnosed for Fibro is not easy and going to a doctor telling them that is what you think you have is not a good idea either. In order to diagnose you with FMS they have to rule out tons of other conditions like Lupus, or Arthritis, sickle cell, etc. (took me 2 yrs to be diagnosed but that was before so much info about it became known) So it can be costly to get a final diagnosis. Sucks I know. Keeping a pain journal is smart, it helps not only you but your doctor track how far back this pain goes as well as incidents that could have caused trauma to your body to cause the on set of pain.
Try looking online for a fibromylagia trigger point chart. What this is, is a chart that shows you the 18 or so pain points that majority FMS patients experience heightened levels of pain in. they are all over the body. . shoulder, neck, arms, legs, etc. This is very helpful in helping you determine where you experience pain the most. To me you could also have Arthritis and there are various kinds to look up. Some ppl are born with Arthritis and some acquire it earlier on in age than normally. At 29, I have arthritic bones but not arthritis, yet.
To me it does not sound like Fibro, more so arthritis, these two share a lot of the same symptoms. Fibro not only hurts the joints and muscles but extreme fatigue kicks in as well. BUT I am no doctor and others may think it sounds like FMS and here-in lies the problem, it is very HARD to properly diagnosis fibro because our symptoms are all over the place!!
A friend of mine had similar symptoms as you, mostly lower back and extreme pain to touch, she had a spinal problem and a disc issue, something about her discs or bones being rubbed down and she just had surgery three days ago They initially diagnosed her with fibromyalgia. I'd say going to the ER to get xrays, MRI's and or a BONE SCAN would be ideal BUT do not tell them you think you have anything. Let it be fact finding for you and the doctors so that they take you seriously because honestly once you say FIBROMYALGIA to most docs they will think that maybe you are looking for SSI or meds. . sad but true.
Try going to pain clinics but most have to be referred by a doc so heading to the ER and talking to a doc after your exams and expressing that you do not have a regular doc and would like a referral to a Pain clinic would be helpful or to take a bigger leap, make an appt with a Rheumatologist as they are the ones who can tell you if you have arthritis and what to do, etc. Can you get insurance through the state that you live in like county insurance, government insurance?? Look into it if you do not know. . .without it, I would be lost and under a bridge in pain!
for over the counter meds try MIDOL, yep the cramp medication. When I do take meds which is rare, Midol is all i need. The caffeine kicks in and I am perky and literally pain free, now it may not work for everyone but it's a start. For sleep the MIDOL night time works wonders!!! Muscle relaxers may help you as well. Taking things like vicodin or percocets are not useful (in my opinion when it comes to dealing with pain) they just drug you up and keep you numb without helping to release the pain. Try lidocaine pain patches, they are expensive without insurance and may or may not work but if you can get a scrip for them somehow down the line, give them a try. I have painful wrists and ankles hurts to stand or do anything so I place the patches in certain areas on my wrists and ankles then wrap them lightly with a med wrap and let it numb it overnight. . .
Now take a look at your everyday physical work. To help alleviate pain you need to find out what is causing the pain to flare up. If you stand at work all day, consider buying two different pairs of comfy tennis shoes like Reebok Tubes or new balance, etc and alternate during your shift. If you sit for long periods make sure you are ergonomically correct. If your shins hurt try pressure socks, hot and cold alternating showers. Sleep with splints on your feet and never walk in the house barefoot always have a comfy pair of shoes with good support.Try doing some light yoga if you don't already especially first thing in the morning, loosen those joints and release some of the tension. Try getting deep tissue massages, they hurt but they dig deep to release the knots. Acupuncture is amazing for releasing energy and helping you to relax. Do you sleep enough? if not try taking a sleep aid like melatonin, over the counter and works great for some. If you were shoes like high heels, don't for a few weeks and see how your body react. Do you notice you have pain escalations during the weather changes?? That is known to happen to anyone experiencing chronic pain. . .there are places now that sell TENS units without a doc scrip, they can be pricey but worth it. A TENS unit incase you don't know is a small device that can be carried on you like a cell phone on your hip that has electrode patches that you place on the painful parts of your body and you control the amount of electricity you want to pulse to that area. . .most helpful thing ever. You can wear it and no one will know you have it on. . it's that small and compact, athletes use them which I think is why they are becoming more popular.
Also changing you diet can help, eat more fruits like grapefruit or oranges, etc. There is a (I dont know what to call it) system of ruling out foods to see if it can help or add to your pain. . .
