Hello everyone. 
So I have been dealing with major stress last year and since last summer I have been experimenting a lot of unexplained physical pain in my chest and lower back and anal pain too, and tingling/pins and needles sensations in my legs and feet, it's there almost tge whole time but it feels worse in some positions like when I'm laying down or exercising the tingling become very sharp. 
Went to the doctors +10 times but always the answer is the same, nothing is wrong, no vitamin deficiency or anything else either, it kept getting worse and worse until I started taking antidepressant five months ago (Cymbalta) 60mg then after two months all the physical pain is gone except the tingling, it's really driving me crazy and I can't ignore it especially the fact that it's been going for a long time, does anyone here have a similar experience?  And if yes did it go away eventually?  Thanks for reading and hope y'all a happy and healthy life :)
