First time this year I had a bacterial skininfection and an inflammatory immune response all at the same time, caused by a coinfection. So I don't want to take that into account.
The other one, first week of June, took a while to get over it. I couldn't say if it set me back, cause I'm dealing with some 'external' factors giving me a lot of stress.
I'm sorry I can't be of more help.
I felt though that whenever I get a cold/bronchitis or something else, that my joints hurt much more. You have been overdoing it too, so that may also cause that stiff feeling.
