Severe pain due to patellar tendinitis, should I quit this college's semester? ADVISE PLEASE?

If the symbol have a long, drawn out tail for the u, then it stands for micrograms, which is a smaller mass than micrograms (mg). 50 ug would be equal to .05 mg

I have chronic hindmost pain, enjoy had since 11/12/97, next to 3 back surguries , walking make worse, any ideas?

thats microgram. one ug = one thousandth of a milligram(mg)! so 50 ug = 0.05 mg

If I own shin splints from running should I continue my running or stop and if so how long should I stop?

50ug is 50 micrograms. There is 1000ug in 1mg (Milligram)and 1000mg in 1gram (so 50ug is 20 time smaller than 1mg) (1ug is 1millioneth of a gram) if that make sence
