Since working at a particular plant nursery I noticed myself feeling sick almost weekly. The workplace is very run down and I fear that something in the nursery reacts badly with me. It could be the unhygienic water that is collected from the road, or it could be something in the soil or the chemicals they use. Just two weeks ago I become very sick and went to hospital but they couldn't help. I was getting similar symptoms to meningococcal as well as other pains. Before working here I was very fit and healthy and almost never sick.

Does anybody have any ideas as to what it could be? I'm still in bed after days and I'd really appreciate any knowledge. Thank you very much in advance to all responses.
