What you have is KDS, Knife Deficiency Syndrome, and of course you have it without owning a khukuri!
Jim Clifton and I (the only sane members of this forum) are pursuing research as fast as we can (keep those donations coming in, folks!) but for now, preliminary results indicate early detection and treatment is the most important thing. As in all deficiency diseases the deficiency must be rectified -- if you try to ignore the symptoms they will not go away by themselves. Buy a khukuri as soon as possible -- do not delay treatment! The deficiency only gets worse with neglect.
Delay only long enough to determine exactly what sort of deficiency you have -- there are several varieties and numerous subvarieties, each with its own specific remedy. You clearly have the variety known as HIKDS, Himalayan Imports Khukuri Deficiency, and you seem to have the subvariety M43 Deficiency -- but it could be one of the other similar subvarieties. If the KDS is misidentified, even the wrong remedy will relieve symptoms but only temporarily -- for instance if you really have a deficiency in 12" Siripatis a M43 will seem to cure the deficiency -- and in fact it will have a very good effect; you will feel better than you've ever felt before -- but after a time, perhaps months, perhaps only a week or even less in severe cases such as Blues had for a while -- you will begin to realize you still have a deficiency, which can only be relieved with a 12" Siripati.
It is also possible to have more than one variety of KDS at the same time. In those patients the problem is identifying which is the most severe deficiency so that can be remedied first....
