Last Night's Mysterious Visual Experience on Screens
My fiancée, a 38-year-old woman of white Hispanic descent, experienced some unusual visuals while watching television and using electronic screens last night. She is currently taking Adderall, Lexapro, and a multivitamin, and has a history of diagnoses including Borderline Personality Disorder (BPD), depression, ADHD, PTSD, and anxiety. Earlier, she had ingested approximately 20mg of a THC tincture sublingually. Given her high tolerance, she typically needs to consume over 50mg to notice any effects. This particular tincture was obtained from a licensed dispensary, and aside from her routine medications, she hadn't taken any other substances or alcohol. Having been on her daily medications—which include an SSRI and Adderall—for over two decades, she ingested the tincture about 5 to 10 minutes before she noticed the unusual visuals. While watching TV, she began to see what she described as "strings of diamonds" or "sparkling visuals" across the screen and on other devices. This visual distortion persisted for approximately 20 minutes, after which she experienced a mild headache that continued into the following morning. It's worth noting that she frequently suffers from headaches and migraines. I turned to online resources in search of an explanation, but the predominant suggestion was "THC overdose," which she did not experience given her significant tolerance and lack of any typical high. The only aberration was the aforementioned visual phenomenon. I’m seeking insights into what might have caused this incident. Upon discussing it with her the next morning, I wondered if the tincture had been contaminated with another psychoactive substance. If this were the case, perhaps the visuals had emerged without her feeling high due to the SSRI's attenuating effects. However, this possibility seems unlikely considering the product's purchase from a licensed dispensary.

It sounds like your fiancée had an unusual experience with visuals after using a THC tincture, and it's understandable to seek clarity on what may have caused this. While her history and concurrent medications may complicate the situation, we can consider a few possible explanations for the visual phenomenon she experienced.
Main Points
- The combination of THC with her current medications might have contributed to unusual visual effects.
- Visual disturbances can arise from various factors, including substance interactions, sensitivity, or even anxiety.
- Monitoring symptoms and making informed decisions about use may be helpful moving forward.
Explanation
THC (tetrahydrocannabinol), even at low doses in someone with high tolerance, can potentially lead to atypical sensory experiences, especially if combined with SSRIs like Lexapro, which can affect perception. The sensation of “strings of diamonds” or visual distortions could be a benign side effect of THC, particularly if she has not used it in a while. It's also plausible that her routine headaches may have contributed to the experience, as headaches can sometimes accompany sensory distortions.
There's less likelihood of contamination with another substance if the tincture was obtained from a reputable source. However, individual reactions to combinations of substances can vary, and the interactions could lead to unexpected effects, especially when combining THC with other psychiatric medications.
Next Steps
- Monitor Symptoms: Keep a log of any future experiences along with the dosage of THC or other substances used. Note if similar visuals occur and the duration.
- Hydration and Rest: Ensure she stays well-hydrated and rests, especially if she experiences headaches or lingering effects.
- Evaluate Anxiety Levels: Consider reflecting on her anxiety levels during the incident or since any recent life events; stress can amplify sensory sensitivity.
- Be Cautious with Dosage: If deciding to use THC again, she might want to start with a lower dose to gauge her reaction, as the interaction with her medications can alter effects.
- Consult with a Pharmacist or Specialist: If visual disturbances occur again or if the headache persists, it’s advisable to discuss with a healthcare provider or pharmacist who understands drug interactions.
This approach prioritizes her well-being and encourages careful monitoring while maintaining hopeful outlooks on potential future experiences. Please reach out if you need further help or insight on managing the situation.

Understanding Elevated AST Levels When Other Liver Functions Are Normal
Profile: 44-year-old male, height 6'1", weight 188 lbs, Caucasian, non-smoker, occasional alcohol consumer, no prescribed medications, uses some dietary supplements including a multivitamin, green tea extract, pomegranate extract, and beetroot extract. During a recent check-up, most results were satisfactory; however, a single liver enzyme—AST—was reported slightly above the established reference range. While bilirubin and ALT levels remained within normal limits, this raised a few questions. Additionally, the day prior to the tests, I completed an intense run and consumed a glass of red wine. Over the past couple of months, I also engaged in intermittent fasting for weight loss, during which my weight decreased from 196 to 188 pounds. My BMI stands at the threshold of 25, reflecting that I maintain a relatively active lifestyle. For context, my liver enzyme levels had been normal for the prior two years, and I typically drink alcohol 1-2 times weekly, mostly red wine. All other components of my metabolic panel and complete blood count were within acceptable ranges. Given that both bilirubin and ALT levels are normal, how serious should I consider the elevated AST reading? Could this elevation be linked to my recent running and fasting regimen, or should I be vigilant for other potential health concerns?
Delayed Menstruation
During some intimate interactions, I (26, male) was wearing boxers while she (26, female) was fully unclothed. We engaged in actions that resemble sexual activity, including rubbing and pressing against her vaginal area. Although there was no ejaculation, there was some precum involved. Initially, I didn't worry much as I had come across information suggesting that such activities are generally safe when clothing is involved. However, considering that she is currently in her fertile period, I now feel concerned because her menstrual cycle is two days overdue; she typically has a regular cycle. Additionally, she usually experiences pronounced PMS symptoms, yet this time she hasn’t noticed any signs despite her period being delayed. I'm making an effort to remain calm and avoid alarming her, but I'm increasingly anxious and fear that something might be amiss.
Duration of Hives: What to Expect
Recently, my teenager accidentally sprayed body mist from Bath & Body Works on my 2-year-old, who has no prior health issues. Instantly, she developed hives across her skin and face. We contacted a nursing hotline for advice and have since bathed her in lukewarm water several times, administered Benadryl, and used hydrocortisone cream for relief. Additionally, I applied some previously stored breast milk, which seemed to improve her condition a little before bedtime. However, upon waking up, the hives persisted in various spots on her body. Despite taking Benadryl and using cream, she has been scratching so much that it's causing her to bleed. I had hoped that washing off the irritant would lead to a quick clearing of the rash. How long can I expect the hives to last after eliminating the allergen?
Throat Discomfort After Covid
A 56-year-old woman weighing 170 lbs, previously diagnosed with ovarian cancer, is currently not undergoing any form of treatment after completing chemotherapy and PARP inhibitor therapy. She is not taking any medications at this time. She has a medical port located on the side of her throat where the discomfort is occurring and has had dental implants as well. Prior to contracting Covid, she experienced a sinus infection for which she completed a full regimen of antibiotics. During a two-week period with Covid, she suffered from severe throat pain, mild fever, and considerable body aches. Gradually, her health improved, and she resumed her usual activities, including socializing and shopping by the end of the week. However, last night, she began to experience an unusual type of throat pain. It feels as if a knuckle is being pressed into the side of her throat, with the pain radiating towards her ear. Additionally, she perceives some discomfort in the facial nerve. Given that her port connects to the jugular vein on the affected side, albeit lower than the site of pain, she is concerned about whether this indicates a serious issue or if it is merely a lingering effect following her viral infection.
Concerns About a Toenail Change
At 28 years old, I recently experienced a distressing change with my toenail. Approximately two months ago, a dark brown spot appeared on my big toenail, accompanied by some discoloration along its edge. In the last week, I've observed that this spot has enlarged and lost its circular shape, while the surrounding area has darkened. Additionally, I've been dealing with a sharp, penetrating pain in my big toe, which feels as if it's coming from the bone, and at times, an uncomfortable burning sensation radiates from it. The ache has now spread to my foot as well. After consulting a physician, I was informed that it is just a bruise; however, I have no recollection of injuring my toe. Given these symptoms, I can’t help but wonder if this is something more serious that warrants concern.
