Did I understand this right, taking a ruler left horizontal to your nipple, walking 2-3 cm left and at this point reorient the ruler to vertical direction and walk again 2-3cm in upper direction guides you to perrin's point?
At that position I feel no tenderness, but on other positions. I'm masking if continuous manual therapy might bias the point of interest.
I've hypothyroidism, too. But they told me it was too weak to feel all the symptoms plaguing me.
I still don't understand separating other diseases from ME/CFS when they cause the same set of symptoms. ME/CFS is afaicu a syndrome, a set of symptoms with possibly different underlying reasons.
