I truly appreciate everyone help and suggestion.
Is till a long process till getting a diagnosis. My GP just trying to eliminate the other possible potential causes by doing blood test on vitamin D and b12 defiency for both osteoarthritis and RA, as well as antigens for RA, inflammatory markers. Actually I have very high but just under normal b12 reading last time, good thing of repeating it again that might explain my occasional hands and feet weird feeling. My GP automatically thought I had been vitamins b supplement which I didn't. Most people have deficiency and can cause back pain but my last reading was normal but higher range along with slightly abnormal iron studies.
My symptoms so varied...but only specifically on the left side, back pain, hip pain, pelvic, electric sharp pain down the leg and foot all sound very sciatic like, intensit of pain changed with positions, rest and physical activity. Now it seem also having left lower abdominal in the past 2 weeks I get some occasional discomfort in the lower abdominal but so mild I didn't rise such concern to GP just watching. Is already confusing enough...I really hoping when Neptune transit in 6th house goes direct I can get some clearer answer or if lucky enough all these Neptunian energy will just goes away for the best!
