Mysterious Joint Pain

[Guest guest]

I have noticed that I get terrible joint pain in some buildings, and then none

in other buildings. I have been traveling a lot these past few years. I stayed

in one Manhattan apartment (old, railroad type) where I had joint pain as long

as the heating was on. Once the warm weather came, and the heating turned off,

the joint pain stopped.

I was in a serviced apartment in England, another old, but renovated building,

where I had terrible joint pain. I then moved to a studio apartment where the

joint pain again disappeared.

I am now back in the US in a sublet apartment, post war, typical Manhattan

midtown apartment, and the joint pain is back with a vengence. I am really

wondering if this pain is connected to the buildings I'm in, and what in these

buildings could be causing it. This building is in a high traffic area, and

there is not much air going through the apartment, although you can open the

windows. The air is just not fresh though.
