Pain in lower legs with swelling around tendons

[Gitanshuma]

I am 40 yrs old female.I hv a problem of insomnia for last 12 years & on medication .For last 2-3 yrs I got swelling in my lower legs.I went through so many tests but no result (thyroid,NCT,Doppler,RA factor,CRP,Antigen etc) but no use .4 months back I got severe pain in my legs around ankles (in Achilles' tendons with swelling) I couldn't even walk ...with wrist, back & hip pain.Then Dr gave me ferritin test along with vit D& vitb12 test & the results were shockingly low .I m taking supplements for last 4 months but very little improvement. Wrist pain & back pain has gone but the swelling & pain in tendons are still thr. Not able to walk .Ferritin injunctions& vit b12 injunctions hv given to me ,vit d 60000 iu i m taking once in a week. Please help if someone has gone through similar problems. How long I hv to suffer with this deficiency.

Thanks
