My dr believes I have shingles but I have no rash. Pain started in mid back and moved to right side front under chest area. Now the pain has moved to the center of my back and it seems to be on my spine. Any sudden movement causes excruciating pain which is sudden but stops when I change position. I usually scream due to the intensity. Also having pain in both knees and vague numbness down my legs … they feel very strange. I am into day 8 of symptoms and day 5 on Valtrex. I am seeing no improvement except no longer tired. Is this internal shingles? There seems to be limited info on this condition …and I’m uncertain where to turn and concerned this could take a worsening turn. Has anyone here been to an infectious disease dr or other specialist to treat this. Also I’m interested to hear of others have experienced similar issues and how they dealt with it .
