I am very relieved to hear that you had aspiration biopsy of your lymph-nodes (I assume your doctor did that ) and that all results came buck negative
. I was very worried about that ... Yes, some people have them enlarged for life without any particular reason, but it is always good to check it since it is not a "normal" occurrence.
Yes - long running is not good for a body at all. Since whole "jogging" craze started there was humongous increase of knee and hip problems in very young people
, but nobody is talking about that
. Maybe "joint specialists" enjoy tremendous amount of a new revenue in the recent years LMAO.
Anyways - fast walking and cycling will give you the same benefit of calorie loss without possibility of an injury :D
