Its ok, I get them often, just the usual you know lack of sleep etc. No big deal just sore ...learn to live with them.
I aint got much choice really.
I do not allow my daughter to use the word 'can't'. Not because of the negativity so much as that we misuse the word 99% of the time. For instance, you could have said, "I can't live with these headaches." Obviously, you can. Or when we say, "I can't wait for...." Unless it is water or medicine or summat like that, you probaby can and often have little choice other than to wait for it!!
Not my rule though to be fair. Got that from my Sifu.
