DS is 5.1 and his glands are really up.
2 weeks ago, I noticed he was tired and thought that it was because he was near the end of term. He went to school fine for Mon-Thurs but then the school called to say that he had a high temp and that he could come back the next day if he was fine in himself. Woke up Fri and temp totally vanished, totally fine, full of energy so went to school and teacher said he was fine all day. Glands were up though. Continued to be totally fine and lots of energy, went to school etc, for another full week but glands up the whole time. Yesterday we went out and he started complaining that his leg hurt so we carried him to the car and went home. Had a mild temperature but quite acute pain in knee(s)? We are sure he didn't hurt himself as we were with him the whole time yesterday. Woken up today, glands up, legs hurting but no temp and he is lively. What's wrong with him - would be really grateful for any ideas. His glands are massive!
