Leg pain/locking up knee?

Two questions really... (1) Knee Pain (2) Leg Pain?

• (1) Knee Pain; For about 2/3 weeks I have had knee pains, on the inside of my knee and bottom front. It hurts mostly when I walk up and down the stairs, and if i put pressure on it, when it is bent. Any ideas? (2) Leg pain; I have had these leg pains for maybe about 3/4 years. I know, you probably think that I should know what it is, if I have had it this long but I don't. Basically, it is just a REALLY bad pain sometimes in the lower part of my leg, and sometimes in the higher part of my leg. Now, It kills. It is so painful. I have lost sleep, and I hardly cry about anything like this, but I have cried about it. I have been to the doctors because before now, about maybe two years ago, I used to keep my mum awake because of it, and she took me to the doctors, who made me have a blood test. . . They found nothing, but still now i have the pains, i don't want to go to the doctors i am terrified of injections and i don't want any more (last time Cervical Cancer jab people came in, they wernt allowed to inject me the second time because i fainted and was sick, and the second time when they were injecting my friends, i fainted just because i knew what was happening!) Any ideas?! Would relieve a lot of pain if i found out what it was! xx

• Answer:

  I know that there is a muscle that runs down the inside of your thigh who's tendon connects right under the front of the knee cap. If this started hurting sometime when you were twisting or maybe getting up it may have caused stress on that tendon. I would try icing it on and off for a couple days and trying to rest it as much as possible. If that doesn't help then you may want to see a doctor about it. I'm not sure that I can help you with your second question.
