this isn't really pregnancy related but I just want to see if anyone knows what might be going on or if anyone else has the same problem.

so occasionally I get these horrible aches in all the joints on the left side of my body. it a only the left side. my elbow and knee especially. I have talked to doctors about it but they haven't ever taken me seriously. it doesn't happen all the time and I can't really say I have noticed a trigger. a doctor told me once it was tendonitis but that doesn't make sense cause it is in both my elbow and my knee and on my left side. I am right handed. tendonitis is typically only on your dominant side. it's not debilitating but it is really really annoying. makes me feel bad all day and puts me in a bad mood. right now it is making it realkyvhard for me to sleep even though I'm tired.
