I dont know what you have, but ask your doctor for blood and urine tests and get an abdominal ultrasound done, better to get everything checked that you can to find the root cause.
Well I don't have a short term answer. But, for the bone pain you should get a complete blood count, chemistry profile and a bone scan. You can take NSAIDs and see if that helps or Tylenol. Since you are having other symptoms maybe you should get an EKG, 24 hour monitor and an echocardiogram to check your heart. You may have an arrhymia too. If you do usually they are benign but get off all caffeine, and supplements such as CoQ10 and see if you feel better. Also the wet burbs may be a ulcer and/or GERD. Probably need a upper GI. Sometime having GERD will give you papitations. For that you can try Zantac Maximum strength and take 1-2 per day. It takes a little longer to work than prilosec and it doesn't give you diarrhea. But you definitely need to get diagnosed. Go off these things a week or two ahead of any scan.
I don't know how likely this is, but a disease called Bartonella is known to cause neurological symptoms, neuropsychiatric symptoms (depression & anxiety), bone pain, sores, headaches, and even GI symptoms. It was thought to be a self limiting infection in all but the immuno suppressed, but it is turning up more and more as an infection in its own right. Most doctors are unaware of it. I have it and I had to spell it for my PCP after another doctor diagnosed me, as she had never heard of it.
There are two primary versions: b. henselae and b. quintana. They are carried my multiple different insects. It is usually treated with a few months of Rifampin or Levaquin or Erythromycin. A lab called IGeneX does more advanced testing than most labs and is more likely to find it.
