I have been practising shamatha meditation 6-7 hours a day for the past 8 months (in retreat) and a week ago I started experiencing pressure in my the left and right temples of my head. The pressure increases if I continue to meditate. It remains even after the meditation, i.e. it is present most of the time. The pressure is so strong that it's difficult to meditate. It fades away if I lie down. But after almost a week of resting without meditation, the pressure is still constant. Currently my practices are almost at a standstill. So I'd really appreciate any advice on this matter! Thanks!
