There is no need to be sorry.
Keep asking questions sweetie. It is perfectly fine.
Well I think the Fatigue depends on the individual.
It is a very individual thing.
If you feel that you cannot do the things that you used to be able to do then that may be fatigue to you.
If you feel that you are always tired and exhausted and never refreshed that can also be fatigue.
PLEASE make an appointment to see a Rheumatologist or your Primary Doctor.
You need to really talk to or see a Doctor to get some help for your symptoms.
I am so sorry for your pain.
I have extreme fatigue. It is overwhelming. I totally understand.
Send me a PM if you want and I will try my best to help you.
Just do not give up!!
