I believe i have shingles. lower back burning pain and rash presented apx 1.5 wks later, which spread around my torso (rt side). i have developed small lumps under the skin where the pain originated. could this be lymph swelling? it is 3/4 down back?

What you mean by glandular is unknown. The shingles label may be correct. It is triggered by re-emergence of the varicella virus along the path of the nerve root where it has been hibernating. The body eventually renews its immune resistance to this viral process & it fades. There are meds that help it fade faster.

If you mean lymph gland swelling, that is unlikely as there are no lymph glands in the lower back. It is not feasible to provide a meaningful opinion without examining you. If the lumps more than double in size, ulcerate, bleed, or appear in the other areas of the body, it would be prudent to see a doctor.
