I'm sorry to hear you're experiencing this persistent pain. Pain on the right side from the shoulder down to the leg that worsens before your periods and eases afterward, despite negative scans and checks, can be quite distressing.

This pattern suggests a possible link to your menstrual cycle, which might indicate conditions related to hormonal changes or gynecological issues such as endometriosis or pelvic congestion syndrome. Endometriosis, for example, can cause cyclical pain that worsens before menstruation and improves afterward, even if imaging tests are normal. Hormonal fluctuations can also affect nerve sensitivity or muscle tension, contributing to such pain.

Since scans and other checks have not revealed a clear cause, it is important to consider:

• Gynecological evaluation: A specialist in gynecology can assess for conditions like endometriosis or other menstrual-related disorders.
• Pain management: Addressing symptoms with appropriate medications or therapies.
• Further investigations: Sometimes, diagnostic laparoscopy or other specialized tests may be needed if symptoms persist.

Given the complexity and impact on your quality of life, I strongly recommend consulting a gynecologist who can provide a thorough evaluation and tailor a management plan suited to your situation. If the pain worsens or new symptoms develop, seek medical attention promptly.To narrow down potential causes, we will need some more information.I understand you're experiencing right-side pain from your shoulder to your leg that worsens before your period and improves afterward, even though scans and tests haven't found anything.
