Unexplained Forearm Bump: Seeking Insight
I’m a 28-year-old male, standing at 5'6" and weighing roughly 180 pounds. I maintain a moderately active lifestyle, exercising about three times a week. Of Caribbean descent, I do not engage in smoking or substance abuse and consume alcohol infrequently, typically only three times a year at most. Recently, I’ve become aware of a lump on my forearm—it's been present for several years. It isn't causing me any discomfort. When I touch it, the texture resembles that of a small stone but has a certain softness to it. It's neither too hard like a rock nor too squishy. I plan to mention this to my doctor during my upcoming appointment, but for now, I’m curious about what it might be. Additionally, I’ve noticed that while I’m lying down and using my phone with that arm, I experience an itchy sensation at the base of my hand. This itch only occurs in that specific position, and I need to adjust my hand to alleviate it. Thank you for taking the time to read this. Your insights would be greatly appreciated.

It's great that you're being proactive about your health, and mentioning the lump and the itchy sensation to your doctor is an important step. The bump on your forearm could likely be a benign cyst, such as a lipoma or a sebaceous cyst, especially since it’s been there for years without causing discomfort. However, it’s wise to have it looked at to rule out any other conditions. The itchy sensation when lying down may be related to nerve compression or irritation in a specific position.
Here’s a structured approach to address your concerns:
Understanding the Lump and Itch
-
Possible Causes of the Lump:
- Lipoma: A benign fatty tumor, usually soft and mobile under the skin.
- Sebaceous Cyst: A small lump beneath the skin, often filled with a substance produced by sebaceous glands.
- Ganglion Cyst: A fluid-filled sac often found near joints or tendons.
- While these are generally harmless, seeing a healthcare provider is ideal for accurate identification.
-
Possible Cause of the Itch:
- Nerve Compression: Certain positions can compress nerves, leading to itching or tingling.
- Contact Dermatitis: An allergic reaction to something that your skin touches, though this seems less likely if it's position-dependent.
Next Steps to Consider
- Observation: Monitor the lump for any changes in size, texture, or symptoms (like pain or redness) over the next few days.
- Adjust Positioning: When lying down and using your phone, try to adjust your arm and hand position to see if it reduces the itching. You can switch hands or rest your forearm on a pillow for better support.
- Document Symptoms: Keep track of any changes in the lump or the itch. Note if certain activities trigger the itch.
- Plan for Your Doctor’s Appointment: Prepare to describe your lump and the itching sensation to your doctor, including how long you’ve had it, any changes, and when the itch occurs.
It's commendable that you're addressing your health concerns actively and preparing for your doctor's visit. If the lump changes or if the itching persists or worsens, definitely escalate your concerns during your appointment.

Assessing the Need for Medical Attention After a Cat Bite
I’m a 35-year-old female with a hypothyroid condition, currently on medication including Synthroid, ferrous sulfate, and vitamin B12. Earlier today, my cat bit me after spotting another feline outside; it seemed to be a case of redirected aggression. The bite resulted in several puncture wounds on my ankle, and I also received a scratch on my foot. I promptly cleaned the injuries and applied a bandage, but they still have a slight sting. After researching online, I learned that bites from cats that penetrate the skin should be evaluated by a healthcare professional without delay due to the potential risk of infection, particularly when they occur near bones. Since it is currently midnight, my only option is to visit the emergency room, as there’s no urgent care facility in my area. I'm hesitant to overreact or impose a burden, so I’m wondering if it’s advisable to wait until morning for a medical check-up, or if it is critical that I seek immediate attention for these wounds.
Experiencing a Strange Tingling Sensation in My Foot
Greetings! I stand at about 5 feet 6 inches tall and weigh roughly 155 pounds based on my most recent measurement. Identifying as female assigned at birth, I’m 16 years old. I do not smoke and I don’t reside with anyone who partakes in smoking either. Additionally, I’m currently not taking any medications. The only health concern that comes to mind is some hip issues that have been affecting my knees, but these have been manageable lately. I’m not particularly anxious about my situation, rather I’m curious about its underlying cause. I’ve noticed that occasionally, as I exhale, there’s a tingling sensation that travels down my legs and settles at my feet. This experience isn’t frequent, and I’ve ensured that I'm not hyperventilating. I maintain an active lifestyle; I participate in color guard, swim regularly, and recently attended a two-week band and guard camp with practice sessions extending from 1 PM to 9 PM, along with various eight-hour guard practices scattered throughout my summer break, which just concluded. In addition to the tingling, I’ve been experiencing stiffness and soreness on the top of my left foot for the last few days. It tends to hurt when I’m barefoot and sometimes even when I’m flat-footed. The tingling sensation has emerged in the last few days, while the discomfort in my foot has persisted for about two weeks. As mentioned earlier, I’m not overly concerned; it simply feels unusual, and I’m keen to understand what might be causing it.
Concerns About a Possible Tumor Near My Tonsil
I am a 22-year-old woman, weighing 222 pounds and standing 5 feet 6 inches tall. Since December, I have been experiencing a condition that resembles geographic tongue, but it's only present on one side of my mouth. Many individuals in the AskDentists community have suggested it might be geographic tongue, but I'm starting to doubt that explanation. Over the past month, I’ve been having intermittent feelings of tightness and discomfort, resembling a globus sensation, alongside pain radiating down the left side of my throat, which coincides with the area where the geographic tongue appears. About two weeks ago, I woke up with notable pain and, upon inspection, discovered a white spot on my anterior tonsillar pillar. This spot disappeared within two days but left behind what appears to be a persistent lump. Since that episode, I've also experienced discomfort in my left ear and throat, particularly while eating. Today, I decided to examine my throat again. I gently retracted my anterior tonsillar pillar to check for any possible stones and encountered a puzzling finding, which I’ll elaborate on in the comments.
Seeking Answers for Persistent Vomiting
As a 30-year-old woman, I have been struggling with consistent episodes of vomiting for the past two years, and I've exhausted numerous treatment options without success. Despite being prescribed various antiemetics and antacids, none have provided relief. Unfortunately, my condition seems to be worsening over time, leading to deficiencies in essential vitamins and nutrients since I am unable to retain any food. Eating often feels unbearable, as if I have consumed a heavy, intense burden that expands in my stomach, creating discomfort until I vomit, which is the only momentary reprieve I experience. To manage my ongoing issues, I've undergone gallbladder removal and am currently taking a regimen that includes ondansetron, omeprazole, potassium, and iron supplements. For my endometriosis and polycystic ovary syndrome, I've been on Depo-Provera for four years. Additionally, I use diphenhydramine occasionally to assist with sleep and sometimes rely on over-the-counter remedies like Emetrol and Dramamine, along with ginger and turmeric. I am feeling hopeless and overwhelmed by my situation. This past week has been particularly tough, as I've only had one small bowel movement and my abdominal area is very tender. Despite this, I continue to vomit every meal and snack. I’m reaching out for advice: what steps can I take next? What questions should I bring to my healthcare provider to seek effective help?
Seeking Guidance for Ongoing Health Concerns
I'm looking for suggestions on what I should do next regarding my health situation. I'm a 41-year-old female experiencing intermittent joint pain, primarily affecting my elbows and wrists. I visited a rheumatologist in the past, and I've tested positive for IgA antibodies as well as HLA B 27. During episodes of discomfort, I notice elevated white blood cell counts alongside heightened absolute eosinophils. However, my rheumatoid factor has returned negative in multiple tests over the years. I continually hear that I meet some, but not all, criteria for a diagnosis, leaving me uncertain about where to turn or what queries to pursue in finding the underlying issue. I don't have any other apparent symptoms, such as rashes or fever. Any insights or recommendations would be greatly appreciated!
