AMENDED POSTING.
Hello Andrew
I am a mum of four , all grown up now ! I am also a retired nurse.
I am going to be blunt now with you.
You need to get your knee checked out.
There are a number of conditions that this ache may be, note the word may be due to. ALL treatable with good prognosis.
You must get it checked out. Now Andrew I do not normally tell people what to do bcause it can get their backs up and people then retaliiate , myself included, by digging their heels in.
Have u been vaccinated and if so have u been vaccinated against TB?
Now someone on here gave very good advice indeed by advising you to see a paediatrician. I would second that BUT also you need to see an ORTHOPAEDIC surgeon.
The paediatrician can refer you to the orthopod as we call them in the trade!
If u go to A and E and depending on how good they are they may refer you on. Things change and that may not be the case nowadays.
Other options are as follows.
Book an appointment with a private physio, some offer free initial consultations Considering your age and therefore presumably a non wage earner a kindly physio may see u privately for NOTHING!
Another option is to ring the surgery to enquire if they have an in house physiotherapist, that may get the ball rolling. Another option is to tell the school nurse or head of pastoral care.
I worked as a nurse in a Student Health and then also at a boarding school so I know that people in certain age groups have problems. What do your parent(s) say about this?
Anyway it is your knee. At some point which u already are and that is being acknowledged and applauded you have to take responsibility for our own health.
I would start a diary listing signs and symptoms nd if related to exercise, sports, diet etc etc.
So go for it. Enlist the helpof a doctor.
Do you use a laptop? Are you huddled over it resting it on your knee?
Are u living at home or a boarder?
