muscle fatigue

Question
Dear Coach,
I've been working on raising my vertical jump bar, i was successful in quite a short time, from 27 inches to 35 in about 3-4 weeks.
After the obvious gain, i might have gotten too motivated i switched to working out nearly EVERY day, while playing basketball on Wednesdays, and Saturdays (Full court, and i'm known for never slowing down). Lately i've been feeling alot of pain on my shins, supposedly lactic acid, i get really fatigued playing, and i can barely jump up 30 inches. I tried to rest for a few days with massaging my legs with warm water, as well as deep heat cream. I used to run track so im very fast, now i feel very slow, and i can't jump, lowering my capabilities. What am i supposed to do? Info: i'm 5'8, 80-81 kgs, in very good shape, strength and endurance based, Practices made: Wall sits, Step ups, running, Calf Raises. About 300-400 cal raises a day, 7 minutes of wall sits, and about 300 step ups a day
what am i supposed to do, and how short can i get my muscles back, i've  lost NO shape, only effectiveness and im tired
thank you coach =)

Hi Monzer -

First, thanks for contacting me.
Second, you might have a serious problem, so instead of speculating I suggest you contact a health professional.  Begin with your family doctor if you have one.

I sent your message to a physical therapist and here is an edited reply:
Sounds like this athlete may be suffering from "Shin Splints" from overuse.  Also known as an "overuse syndrome."  This can be very difficult to treat in a person who likes to push his body to the limit like your athlete has done.  If left untreated this CAN become a chronic problem.  
He may need to see a professional to guide him through the management of this problem.  
Some initial self remedy........ rest (3 weeks up to 3 months in severe cases), ice and anti-inflammatory.  Avoid high impact activity and jogging or running.  He can engage in swimming and start gentle stretching.
Shin Splints is a condition but may be a symptom of something else like stress fracture, tendinitis, or from bio-mechanical fault of his feet (flat feet or high arches that may need orthodox to reduce stress and improve the shock absorbing mechanism of his legs, etc).  Well, I hope this helps.

Monzer - you sould not mess around with this.   At your age, 3 months seems like an eternity, but if you don't handle this properly it COULD end your athletic career.  
Do the right thing, take this as a serious problem.
